일반물리학 1 — Force and Motion-II: Problem 24

24 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 6-30 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 \( v_s = 5.0 \text{ m/s} \). What is the coefficient of kinetic friction between the block and the floor?
