In an exciting game, a baseball player manages to safely slide into second base. The mass of the baseball player is 77.7 kg and the coefficient of kinetic friction between the ground and the player is 0.48. If it took the player 1.6 s to come to rest. A. Find the magnitude of the frictional forceB. If the player takes 1.4s to come to rest what was his initial velocity
C. What was his initial velocity (in m/s)?
