a 70 kg man and 50 kg woman are in a boat when its motor fails. the man dives into the water with a horizontal speed of 3 m/s in order to swim ashore. if he changes his mind, can he swim back to the boat if his swimming speed is 1 m/s? If not, can the woman change the boats motion enough by diving off at 3 m/s in the opposite direction? Could she return to the boat herself if her swimming speed is also 1 m/s?
