Engineering Mechanics - Dynamics Chapter 15 Given: W 4lb = v 0 10 ft s = a 20 lb = g 32.2 ft s 2 = b 1 s = θ 20 deg = c 1 = Solution: Guess t 10 s = Given W g v 0 0 t τ ab c + () d + W sin () t 0 = t Find t () = t 0.069256619 s = * Problem 15-16 If it takes time t 1 for the tugboat of mass m t to increase its speed uniformly to v 1 starting from rest, determine the force of the rope on the tugboat. The propeller provides the propulsion force F which gives the tugboat forward motion, whereas the barge moves freely. Also, determine the
