008 (part 1 of 2) 10.0 points
A 79.6 kg base runner begins his slide into
second base while moving at a speed of 4.1
m/s. The coefficient of friction between his
clothes and Earth is 0.64. He slides so that
his speed is zero just as he reaches the base.
The acceleration of gravity is 9.81 m/s?.
a) How much mechanical energy is lost due
to friction acting on the runner?
Answer in units of J.
