Engineering Mechanics - Dynamics Chapter 15 Problem 15-42 The man M has weight W M and jumps onto the boat B which has weight W B . If he has a horizontal component of velocity v relative to the boat , just before he enters the boat, and the boat is traveling at speed v B away from the pier when he makes the jump, determine the resulting velocity of the man and boat. Given: W M 150 lb = v B 2 ft s = W B 200 lb = g 32.2 ft s 2 = v 3 ft s = Solution: W M g vv B + () W B g v B + W M W B + g v' = v' W M vW M W B + v B + W M W B + = v' 3.29 ft s = Problem 15-43 The man M has weight
