Two rocks are at the top of a building. Rock 1 is dropped from rest while Rock 2 is thrown horizontally at a velocity of 5 m/s.What is the horizontal acceleration of Rock 2
The horizontal acceleration of the rock 2 is zero.
The given parameters;
initial velocity of Rock 1 = 0
initial horizontal velocity of Rock 2 = 5 m/s
An object falling under the influence of gravity experiences acceleration due to gravity which is always directed vertically downwards.
An object moving horizontally is not affected by gravity and thus will experience no acceleration in the horizontal direction.
Thus, we can conclude that the horizontal acceleration of the rock 2 is zero.

Describe the difference between distance, position, and displacement
Answer:
Explanation:
Position is the location of the object (whether it's a person, a ball, or a particle) at a given moment in time.
Displacement is the difference in the object's position from one time to another.
Distance is the total amount the object has traveled in a certain period of time.

What direction would the net force acting on this box be pointed?
northeast
northwest
southeast
southwest
Answer:
The diagram shows a net 2 N in the north direction and 2 N in the east direction - this would result in (4 + 4)^1/2 to the northeast.
if an inelastic collision takes place, during the collision, what is conserved?
Answer:
An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not.
Mixtures can be either heterogeneous or homogeneous. Which of the following is
characeristic of a homogeneous mixture?
A mixture in which two or more substances are still distinguished (can tell there is more than one
substance).
A mixture in which large particles are suspended.
A mixture in which large particles are not suspended and eventually settle.
A mixture in which two or more substances are evenly distributed (spread out).
Answer:
Option D
Explanation:
There are two types of mixtures

The mixture on which different types of substances are present is called heterogeneous mixture.
Describe how energy is transferred from 1 form to another
Answer:

Imagine everyone in the United States exhibited the character traits we have been discussing. In what ways would America be different?
Now imagine no one in American exhibited any of those character traits. In what ways would America be different?
Answer:
Characterization is the process by which the writer reveals the personality of a character. Characterization is revealed through direct characterization and indirect characterization. Direct Characterization tells the audience what the personality of the character is.

A spacecraft orbiting a planet at an altitude of 120 km releases a satellite that falls towards the surface. The planet has a mass of 5.2 x 10^23 kg and a radius of 2800 km. What is the acceleration of the satellite?
Answer:
Consider a satellite with mass Msat orbiting a central body with a mass of mass MCentral. The central body could be a planet, the sun or some other large mass capable of causing sufficient acceleration on a less massive nearby object. If the satellite moves in circular motion, then the net centripetal force acting upon this orbiting satellite is given by the relationship
Fnet = ( Msat • v2 ) / R
Explanation:
The acceleration of the satellite released from a spacecraft orbiting a planet at an altitude of 120 km and the planet has a mass of 5.2 x 10^23 kg and a radius of 2800 km is 4.426 * [tex]10^6[/tex] [tex]m/s^2[/tex].
What is acceleration?
The term "acceleration" refers to the rate and direction at which velocity varies over time. Acceleration is the change in direction or speed of an object or points moving ahead. The frequent change in direction causes motion on a circle to rise even when the speed remains constant.
For all other motions, these effects increase the acceleration. A vector quantity, acceleration, is something that has both a magnitude and a direction. Velocity is a vector quantity as well.
Given:
The altitude of the spacecraft, h = 120 km,
The mass of the planet, m = [tex]5.2 * 10^{23}[/tex] kg,
The radius of the planet, r = 2800 km.
Calculate the acceleration by the formula given below,
A = [tex]G* m /r^2[/tex]
Here, A is the acceleration, G is the gravitational constant,
Substitute the values,
A = 6.674 * [tex]10^{-11}[/tex] *5.2 * [tex]10^{23}[/tex] / [tex]2800^2[/tex]
A = 4.426 * [tex]10^6[/tex] [tex]m/s^2[/tex]
Therefore, the acceleration of the satellite is 4.426 * [tex]10^6[/tex] [tex]m/s^2[/tex]

im confused on number one
Explanation:
v=?, u=0, a=?, S=22m.
Using the formula, S=ut+½at²
22={0×5}+(½.a.5²)
22=½.a.5²
a=44/25 = 1.76m/s².
Therefore, net force = work done = ma = 48×1.76 = 84.48N.
therefore, power = work done/time = 84.48/5 = 16.896W.

A ball accelerates uniformly at +4.0 m/s2
If the ball was initially moving a +0.20 m/s and the average velocity was +4.2 m/s, then how long will it take it to reach the final velocity?
It will take 1 second to reach the final velocity
Acceleration of a body is the change in velocity of the body with respect to time. This is mathematically represented as;
[tex]a=\frac{v-u}{t}[/tex]
Given the following parameters
a = +4.0 m/s²
u = +0.20m/s
v = +4.2m/s
Substitute the given parameters into the formula to get the time "t"
[tex]4=\frac{4.2-0.2}{t}\\4t=4.2-0.2\\4t=4.0\\t=\frac{4}{4}\\t=1sec[/tex]
This shows that it will take 1 second to reach the final velocity

What combination for distance and mass gives you the STRONGEST or LARGEST force?
Answer:Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.

why does lowered air pressure allow water to boil at room temperature
Answer:
As ambient air pressure decreases, molecules evaporating from a boiling liquid meet less resistance from air molecules and enter the air more easily. Because the vapor pressure can be reduced, the temperature needed to boil the liquid is also reduced.
Explanation:
Answer:
Less force pushes down on the liquid, making it easier for gas to escape.

A car moving along a straight highway with speed of 126 km 1 h− to brought to stop within a distance of 200 m. how long does it take for the car to stop?
Answer: 11.43 sec
solution:
v2 – u2 = 2as
a = (v2 – u2)/2s
= (0 – 352)/(2 × 200)
= –1225/400
= –3.06 m/s2
v = u + at
0 = 35 – 3.06 × t
