Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_163

3/163 The 100-lb block is stationary at time \(t = 0\), and then it is subjected to the force \(P\) shown. Note that the force is zero for all times beyond \(t = 15\) sec. Determine the velocity \(v\) of the block at time \(t = 15\) sec. Also calculate the time \(t\) at which the block again comes to rest. Given from the graph: \(P = 60 \text{ lb}\) for \(0 \le t \(P = 30 \text{ lb}\) for \(10 \le t \le 15 \text{ s}\) \(P = 0\) for \(t > 15 \text{ s}\) \(\mu_s = 0.50, \mu_k = 0.35\)
