Question

Part A The 13-lb block has a speed of 4 ft/s when the force of F = (8t²) lb is applied. The coefficient of kinetic friction at the surface is \(\mu_k = 0.1\). (Figure 1) Determine the speed of the block when t = 2 s. Express your answer to three significant figures and include the appropriate units. Figure v = 4 ft/s F = (8t²) lb v = 148 ft s
