What is the velocity of a football thrown?, when the mass of the football is 0.425 kg, and the momentum is + 10.1 kg.m/s?

Answers

Answer 1

The velocity of the football thrown is approximately 23.76 meters per second.

What is the velocity of the thrown football?

Momentum is simply the product of the mass of an object and its velocity.

This is expressed as;

P = m × v

Where m is the mass of the object and v is its velocity.

Given that;

Momentum P = 10.1kgm/sMass m = 0.425kgVelocity v = ?

Plug the given values into the above formula and solve for v.

P = m × v

v = P / m

v = 10.1kgm/s / 0.425kg

v = 23.76 m/s

Therefore, the velocity of the ball is 23.76 m/s.

Answers

In clockwise direction the propellers rotate as seen from the rear of the plane. If the plane is flying horizontally and suddenly pulls upward, the nose of the plane would veer upward. The correct options are B and A respectively.

The propellers rotate anticlockwise when viewed from the back of the aircraft.

When observed from the rear, an anticlockwise rotation direction corresponds to propellers spinning in the forward direction because the angular momentum of the propellers points directly forward from the plane.

The nose of a plane tends to pull forward when a plane flying horizontally suddenly pulls upward. This is brought on by the direction of the lift force produced by the wings changing.

By raising the nose, the angle of attack widens, increasing the lift force that raises the plane's nose upward. The change in the aerodynamic forces exerted on the aircraft is what causes the nose to rise upward.

Thus, the correct options are B and A respectively.

A car is moving at 30.0 m/s, east in a straight line approaching the red traffic light as shown. The
time it takes for the car to stop is .6 seconds.

What is the acceleration of the car?

Answers

Answer:

–5

Explanation:

u = 30m/s , v = 0(comes to a stop) , t = 6s, a = ?

a = v – u/t

a = 0 – 30/6

a = –30/6

a = –5

A car is moving at 30.0 m/s, east in a straight line approaching the red traffic light as shown. The time it takes for the car to stop is 0.6 seconds. The acceleration of the car is -5 m/s.

What is speed?

Speed is defined as the pace at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined.

Given

u = 30m/s ,

v = 0(comes to a stop) ,

t = 6s

To calculate acceleration we use formula

a = v – u/t

a = 0 – 30/6

a = –30/6

a = –5 m/s

Thus, a car is moving at 30.0 m/s, east in a straight line approaching the red traffic light as shown. The time it takes for the car to stop is 0.6 seconds. The acceleration of the car is -5 m/s.

The variety of species found in an ecosystem is known as its biodiversity. The evolution of organisms following a catastrophe that wipes out an environment is known as ecological succession. Ecological succession boosts biodiversity by expanding the variety of species that exist in a region.

Site characteristics, the kind of events that start succession, interactions between the species present, and more stochastic elements, such the availability of propagules or the weather at the time of disturbance, can all have an impact on the course of successional change.

A 2-meter-long pendulum, is set in motion, at 1.2 m/s, when the pendulum arm is at an angle of 25° from the vertical. Find the speed of the pendulum when it reaches the bottom of its swing.

Answers

ANSWER: Approximately 2.17 m/s.

EXPLANATION: Using the equations of motion for a pendulum, you can calculate the velocity of the pendulum at the bottom of its swing as follows:

v = √(gL(1 - cos(θ)))

Where:
v is the velocity of the pendulum at the bottom of its swing

g is the acceleration due to gravity (9.8 m/s^2)

L is the length of the pendulum (2 meters)

θ is the angle of the pendulum at the top of its swing (25°)

Substituting these values into the equation gives:

v = √(9.8 * 2 * (1 - cos(25°)))

Solving this equation gives a velocity of approximately 2.17 m/s. This is the speed of the pendulum at the bottom of its swing.

Answers

When one of the Charges Q is swapped out for another charge 4Q, there is a force on Q that is 4F strong.

Coulomb's equation of electricity states that the amount of the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance separating the two charges.

Calculation:

Mathematically, F = KQ₁Q₂ /d²

The coulombs law equation gives the magnitude of the force between the items, F, if the initial charges on the two objects are each equal to Q and the distance between the charges is d. i.e. F = KQQ/d².

The force between the charges will now be given as follows if one of the charges is swapped out for a charge 4Q:

A young girl jumps off the edge of a shopping trolley. The trolley is stationary at the moment the girl jumps. The girl jumps backwards. Describe and explain, using the idea of momentum, what happens when the girl jumps off the trolley.​

Answer:

Momentum is a physical quantity equal to the product of mass of the object and its velocity. Since velocity is a vector (a quantity that has both magnitude and direction), momentum is a vector quantity as well. According to the law of conservation of momentum, the momentum is always conserved.  This means that the initial momentum must be equal to the final momentum. Our initial momentum is zero since both, trolly and the girl on it are stationary. When the girl jumps, she has some velocity v. To compensate for that, the trolly will also move with some velocity v, but in the opposite direction so that the momentum stays conserved.

The statements that are true are

What is angular momentum?

Angular momentum is the product of the rotational inertia and angular speed of a rotating object.

How to find which statements are true about the angular momentum

Let

I₁ = initial angular momentum of disk X = Ixω₀ where Ix = rotational inertia of disk x and ω₀ = angular velocity of disk y, I₂ = initial angular momentum of disk Y = 0 (since it is initally stationary) where I₃ = final angular momentum of disk x = Ixω and I₄ = final angular momentum of disk Y = Iyω where Iy = rotational inertia of disk y and ω = their common angular velocity after the collision

From the law of conservation of angular momentum, we have that

initial angular momentum equals final angular momentum

So, I₁ + I₂ = I₃ + I₄

Ixω₀ + 0 = Ixω + Iyω

Ixω₀ = Ixω + Iyω

From the above, we see that

Since I₄ > I₂ = 0,

The angular momentum of disk Y immediately after the collision is greater than the angular momentum of disk Y immediately before the collision.

Also, since I₁ + I₂ = I₃ + I₄,

The angular momentum of the disk X-disk Y system immediately after the collision is equal to the angular momentum of the system immediately before the collision.

So, the statements that are true are

The angular momentum of disk Y immediately after the collision is greater than the angular momentum of disk Y immediately before the collision.The angular momentum of the disk X-disk Y system immediately after the collision is equal to the angular momentum of the system immediately before the collision.

Given that,

weight (W) = 20 Kg

distance = 0.4 m

time (t) = 0.82 sec

As we know,

Power (P) = W/t

To find the mass of the cat, you can use the formula for kinetic energy, which is:

KE = (1/2) * m * v^2

where KE is the kinetic energy, m is the mass, and v is the velocity.

You can rearrange this formula to solve for mass:

m = (2 * KE) / v^2

Plugging in the values given, you get:

m = (2 * 91.7 J) / (4.65 m/s)^2

Solving this equation gives a mass of approximately 2.07 kilograms.

If magnets are knocked around a lot or heated, their magnetism will be reduced or lost. Explain why.

Answers

Answer:

so heating a magnet disrupts the domain walls and it becomes easy for the magnet to become ordinarily misaligned and rotate. so when that happens they are now less aligned and point in the opposite direction to the neighbors causing a decrease in the magnetic field and loss of magnetism

An external force of 5 n is applied to a 10 kg object over a time of 3 s. Determine the impulse of the object.

Answers

The impulse of the 10kg object is 15Ns.

How to calculate impulse?

Impulse is the integral of force over time. The impulse of an object in physics is a term that is used to describe or quantify the effect of force acting over time to change the momentum of an object.

It is represented by the symbol J and usually expressed in Newton-seconds or kg m/s.

According to this question, an external force of 5N is applied to a 10kg object over a time of 3 s. The impulse can be calculated as follows:

Impulse = 5N × 3s = 15Ns

Therefore, 15Ns is the impulse of the object.
