The force F, acting in a constant direction on the 20-kg block, has a magnitude which varies with the position s of the block. Determine how far the block slides before its velocity becomes 5 m/s. When s=0 the block is moving to the right at 2m/s. The coefficient of kinetic friction between the block and surface is Mk= 0.3. F (N) F = 50s s (m)
