A 66.0 kilogram base runner begins his slide into second base when he is moving at a speed of 3.6 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides thus that his speed is zero just as he reaches the base.
(1) Determine how much mechanical energy is lost due to friction acting on the runner?
J
(2) Estimate how far does he slide?
m
