After hitting a long fly ball that goes over the rightfielder's head and lands in the outfield, the batter decides tokeep going past second base and try for third base. The 62.0 kgplayer begins sliding 3.40 m from thebase with a speed of 4.90 m/s.
(a) If the player comes to rest at third base, how much workwas done on the player by friction?
(b) What was the coefficient of kinetic friction between the playerand the ground?
