After rounding second base, a baseball player with a mass of 77 kg slides into third base. The coefficient of kinetic friction between the player and the ground is 0.42. What is the magnitude of the friction force acting on the player? If it takes 1.3 s for the player to come to a rest at the base, what was his velocity when he initiated his slide? Suppose you are pulling a 4.2-kg block across a rough, horizontal surface with...

At a construction site, a 68.0 kg bucket of concrete hangs from
a light (but strong) cable that passes over a light friction-free
pulley and is connected to an 85.0 kg box on a horizontal roof (see
the figure (Figure 1)). The cable pulls horizontally on the box,
and a 47.0 kg bag of gravel rests on top of the box. The
coefficients of friction between the box and roof are shown. The
system is not moving.
