The kinetic energy bc the energy is independent of the gravitational acceleration, and it depends only on the speed and mass. So the last answer
Speed - the rate of change of position.
<span>Speed = Distance / Time. </span>
<span>Common units utilized for speed are meters per second (m/s) or miles per hour (mi/h). </span>
<span>Velocity - the rate of change of position. </span>
<span>Velocity = Displacement / Time. </span>
<span>Common units utilized for velocity are meters per second (m/s) or miles per hour (mi/h). </span>
<span>The main difference between speed and velocity is that speed is a scalar quantity (does not depend on direction) whereas velocity is a vector quantity (which does depend on direction). </span>
<span>Acceleration - Change of velocity over time. </span>
<span>Force = Mass x Acceleration. </span>
<span>Acceleration = Force / Mass. </span>
<span>Common used units of acceleration are meters per second squared (m/s^2). </span>
<span>Hope that helped :)</span>
Answer:
The value of tension on the cable T = 1065.6 N
Explanation:
Mass = 888 kg
Initial velocity ( u )= 0.8 
Final velocity ( V ) = 0
Distance traveled before come to rest = 0.2667 m
Now use third law of motion 
= 
- 2 a s
Put all the values in above formula we get,
⇒ 0 = 
- 2 × a ×0.2667
⇒ a = 1.2 
This is the deceleration of the box.
Tension in the cable is given by T = F = m × a
Put all the values in above formula we get,
T = 888 × 1.2
T = 1065.6 N
This is the value of tension on the cable.

Explanation:
Hola.
En este caso, dado que conocemos la frecuencia con la que la particula gira (ω), 5 Hz o 5 giros de radio de 50 cm (0.5 m) cada uno en 1 segundo, podemos calcular la aceleración centrípeta con:
