A 4.50 kg block is pushed along a floor by a constant applied force that is horizontal and has a magnitude of 41.0 N. Figure 6-30 gives the block’s speed v versus time t as the block moves along an x axis on the floor. The scale of the figure’s vertical axis is set by vs = 5.40 m/s. What is the coefficient of kinetic friction between the block and the floor?
