A 69.0 kilogram base runner begins his slide into second base when he is moving at a speed of 3.9 m/s. The coefficient of friction between Earth and his clothes is 0.70. He slides thus that his speed is zero just as he reaches the base.
(a) Obtain how much mechanical energy is lost due to friction acting on the runner?
J
(b) Evaluate how far does he slide?
m
