KE PROBLEMS

Find KE of a .008kg bullet moving at 500 m/s.

If an object has 6J of KE and moves at 2m/s, how much mass does it have?

Another object has 106J of KE and mass of .5Kg. How fast is it moving?

An 800Kg car moves at two different speeds. Speed one is 8m/s and speed two is 16m/s

How do you predict the KE will be different between these two distances?

Find KE for both speeds.

Are your answers different than your prediction?
