The man M has weight { W }_{ M } and jumps onto the boat B which is originally at rest. If he has a horizontal component of velocity v just before he enters the boat, determine the weight of the boat if it has velocity v’ once the man enters it. Given: { W }_{ M } = 150 lb , v = 3 ft/s , v’ = 2 ft/s , g = { 32.2ft/s }^{ 2 }
