Engineering Mechanics - Dynamics Chapter 15 Solution: On the slope v 1 2 gh = v 1 7.67 m s = t 1 v 1 g sin θ () = t 1 1.56 s = On the flat Mv 1 μ k Mgt 2 0 = t 2 v 1 k g = t 2 3.91 s = tt 1 t 2 + = t 5.47 s = Problem 15-27 Block A has weight W A and block B has weight W B . If B is moving downward with a velocity v B0 at t = 0, determine the velocity of A when t = t 1 . Assume that block A slides smoothly. Given: W A 10 lb = W B 3lb = v B0 3 ft s = t 1 1s = g 32.2 ft s 2 = Solution: s A 2 s B + L = v A 2 v B = Guess v A1
