Question
A 25-kg block shown in the figure rests on a rough surface having a coefficient of kinetic friction of µk = 0.25. A variable force F = (50 +s2) N, where s is in m, acts on the block that will result to spring compression. Determine the power developed (in kW and hp) by the force the instant the block has moved s = 1 m. Assume that the spring is originally unstretched (s = 0) and the block is at rest
