Luna and Angela are competitors in a running competition. Both are leading the race and enter at the same time the last 30 meters. Angela enters the final segment runnning at 4 m/s and "applies" an acceleration of 2 m/s2 while Luna enters the final segment at 3m/s but "applies " an acceleration of 3 m/s2. (a) Who finishes the race first? (Do the calculations) (b) Who is running faster at the end of the race?
Answer:
(a) Luna
(b) Luna
Explanation:
(b)
The final speed can be found by using the third equation of motion:
[tex]2as = v_f^2 - v_i^2\\[/tex]
where,
a = acceleration
s = distance covered
vf = final speed
vi = initial speed
For Angela:
a = 2 m/s²
s = 30 m
vi = 4 m/s
vf = v_fa
therefore,
[tex]2(2\ m/s^2)(30\ m) = (v_{fa})^2 - (4\ m/s)^2\\v_{fa}^2 = 120 m^2/s^2 + 16\ m^2/s^2\\v_{fa} = 11.66\ m/s\\[/tex]
For Luna:
a = 3 m/s²
s = 30 m
vi = 3 m/s
vf = v_fl
therefore,
[tex]2(3\ m/s^2)(30\ m) = (v_{fa})^2 - (3\ m/s)^2\\v_{fa}^2 = 180 m^2/s^2 + 9\ m^2/s^2\\v_{fa} = 13.74\ m/s\\[/tex]
Therefore, Luna will be running faster at the end of the race.
(b)
To calculate the time of completion we will use the first equation of motion:
[tex]v_f = v_i + at[/tex]
FOR ANGELA:
[tex]11.66\ m/s = 4\ m/s + (2\ m/s^2)t_a\\t_a = \frac{7.66\ m/s}{2\ m/s^2}\\\\t_a = 3.83\ s[/tex]
FOR LUNA:
[tex]13.74\ m/s = 3\ m/s + (3\ m/s^2)t_l\\t_l = \frac{10.74\ m/s}{3\ m/s^2}\\\\t_l = 3.58\ s[/tex]
Hence, LUNA finishes the race first.

A box is accelerated from rest along a frictionless surface by a net force of 100N. It covers 40 metres in 5 seconds. Find the mass of the box.
Answer: 31,25
Explanation:
F= 100
[tex]F=ma[/tex]
a=?
x = 40
Vo = 0
We have to evaluate a :
[tex]x = Vot + \frac{1}{2}at^2\\\\40=0+\frac{1}{2}a(5^2 )\\\\80=25a\\\\3,2=a[/tex]
The force formula :
[tex]F=ma[/tex]
[tex]100=m*3,2\\\\31,25=m[/tex]
Un móvil parte desde un punto ubicado a +10 Km del origen ,se mueve en línea recta llegando hasta el Km 60, donde cambia su sentido de movimiento, regresando al Km 32 .Entonces el desplazamiento o cambio de posición y la distancia recorrida son respectivamente: A) 22 km y 78 km B) -22 km y 78 km C) -18 km y 38 km D) -18 km y 18 km E) 10 km y 32 km
Answer:
La opción correcta es la A) 22 km y 78 km.
Explanation:
Dado que el desplazamiento (D) es un vector, su valor viene dado por la suma algebraica de los vectores del desplazamiento de ambos tramos.
Como en el primer tramo movil se mueve en la dirección de x-positiva y en el segundo tramo se mueve en el sentido de x-negativo, tenemos:
[tex] D = (60 km - 10 km) - (60 km - 32 km) = 22 km [/tex]
Ahora, la distancia (d) es una magnitud escalar, por lo que su valor viene dado por la suma del desplazamiento de ambos tramos:
[tex] d = (60 km - 10 km) + (60 km - 32 km) = 78 km [/tex]
Por lo tanto, la opción correcta es la opción A) 22 km y 78 km.

Blue-ray disc accelerates from rest to a constant rotational speed of 466 rpm, it rotates through an angular displacement of 0.250 rev. What is the angular acceleration of the CD?
Answer:
[tex]\alpha =434312\ rev/s^2[/tex]
Explanation:
Given that,
Initial angular speed, [tex]\omega_i=0[/tex]
Final angular speed, [tex]\omega_f=466\ rpm[/tex]
Angular displacement, [tex]\theta=0.25\ rev[/tex]
We need to find the angular acceleration of the CD. Using third equation of rotational kinematics as follows :
[tex]\omega_f^2-\omega_i^2=2\alpha \theta\\\\\alpha =\dfrac{\omega_f^2-\omega_i^2}{2\theta}\\\\\alpha =\dfrac{466^2-0^2}{2\times 0.25}\\\\\alpha =434312\ rev/s^2[/tex]
So, the angular acceleration of the CD is equal to [tex]434312\ rev/s^2[/tex].
You cannot classify matter based on chemical properties. true or false?
Answer:
ture i think
Explanation:
It is false that one cannot classify matter based on chemical properties.
What is a matter?Matter is the scientific term for any type of material. Matter is defined as anything with mass that occupies space.
Matter requires at least one subatomic particle, though most matter is made up of atoms. A pure substance is sometimes referred to as matter.
Solids, liquids, and gases are the three forms or phases of matter. A substance is defined as matter that is homogeneous and has identical parts.
Substances are classified as either elements or compounds. Elements are pure substances that cannot be chemically decomposed into simpler substances.
Chemically, matter can be classified as pure substance elements and compounds, mixture, or impure substance.
Thus, the given statement is false.

Which best describes what the observations have in common? They involve nuclear energy. They involve radiant energy. They involve changes in waves. They involve changes in energy.
Answer:
The answer is "They involve changes in energy".
Explanation:
Energy change is quite important in chemicals because nearly all reactions involve activation energy. They will learn and learn how to utilize different types of energy shifts in the steam cycle. A conversation about what drives chemical processes contributes to entropy and natural energy principles. It may shift from the shape of form. For example, chemicals might change to heat.

Una barra de plata de 335.2 g con una temperatura de 100 ºC se introduce un calorímetro de aluminio de 60 g de masa que contiene 450 g de agua a 23 ºC. Sr agita la mezcla y la temperatura se incrementa hasta 26 ºC. ¿Cuál es el calor especifico de la plata?
Respuesta:
0,0560 cal / gºC.
Explicación:
Cantidad de calor; (Q)
Q = mcΔt; Δt = t2 - t1
m = masa, c = capacidad calorífica específica; Δt = cambio de temperatura
c de agua = 1 cal / gºC
c de aluminio = 0,22 cal / gºC
QTotal = Q de agua + Q de aluminio
Q de agua = 450 * 1 * (26 - 23) = 1350 cal
Q de aluminio = 60 * 0.22 * (26 - 23) = 39.6 cal
QTotal = 1350 + 39,6 = 1389,6 cal
Calor perdido = calor ganado
QTotal = calor perdido
- 1389,6 = 335,2 * c * (26 - 100)
-1389,6 = −24804,8 * c
c = 1389,6 / 24804,8
c = 0,056021 cal / gºC.
Capacidad calorífica específica de la plata = 0,0560 cal / gºC.

Explanation:
An elephant's legs have a reasonably uniform cross section from top to bottom, and they are quite long, pivoting high on the animal's body. When an elephant moves at a walk, it uses very little energy to bring its legs forward, simply allowing them to swing like pendulums. For fluid walking motion, this time should be half the time for a complete stride; as soon as the right leg finishes swinging forward, the elephant plants the right foot and begins swinging the left leg forward.

Describe the role that weathering and erosion play in the rock cycle.
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
