After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, a batter decides to keep going past second base and try for third base. The 67 kg player begins sliding 3.40 m from the base with a speed of 4.5 m/s.
If the player comes to rest at third base, how much work was done on the player by friction with the ground?
What was the coefficient of kinetic friction between the player and the ground?
