A 4.10 kg block is pushed along a floor ...

A 4.10 kg block is pushed along a floor by a constant applied force that is horizontal and has a magnitude of 50.0 N. Figure 6-46 gives the block's speed v versus time t as the block moves 0.5 1.0 along an x axis on the floor. The scale of the figure's vertical axis is set by `v_(s) = 5.0` m/s. What is the coefficient of kinetic friction between the block and the floor?
