A 80-kg base runner begins his slide into second base when he is moving at a speed of 4.3 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base.

(a) How much mechanical energy is lost due to friction acting on the runner? J

(b) How far does he slide? m

Starting from rest, a kid named Billy goes down a slide, which is a height of 2.5 m above the ground. Billy’s mass is 35 kg. There is friction acting on Billy, so that when he reaches the bottom of the slide (at ground level), his speed is only 3.5 m/s. Consider the total mechanical energy of the Earth + Billy system, which consists of kinetic and potential energy. How much mechanical energy was lost due to friction? Give your...

A 4.25 kg block is projected at 5.40 m/s up a plane that is inclined at 30.0° with the horizontal. The block slides some distance up the incline, stops turns around and slides back down to the bottom. When it reaches the bottom of the incline again, it is traveling with a speed of 3.80 m/s. If the coefficient of kinetic friction between the block and the plane is 0.500, how far up the incline did the block slide?
