Hi!
How do i find change in kinetic energy?
Here is the problem:
The rubber ball is dropped 2m elastically off the floor, so its speed immediately after bouncing is the same as immediately b4.
If the rubber ball has a mass of 0.015kg and its velocity is 6.26m/s, what is its change in kinetic energy from immediately b4 the collision to immediately after the collision? Breifly justify your answer.
Do i use this equation, KE = 1/2mv^2?
THANKS!
