[SHOW YOUR WORK] A 2000 kg car at rest at the top of a 1000 meter high hill rolls down to the bottom. a) Assuming no friction is acting to slow
down the car as it rolls down the hill, how fast is it going when it reaches
the bottom of the hill? b) Assuming that there is friction stopping the car
when it reaches the bottom of the hill - how much work is done to stop
the car? c) How much friction force is required to stop the car in 100
meters?
