Q1. A 80 kg man and a 50 kg woman stand side by side at the same end of a 120 kg boat, ready to dive, each with a 5 m/s velocity relative to the boat. The woman dives first and the man second. 1) Verify that the velocity of the boat right after the woman has dived is v = -1.00 i m/s. Here i is the unit vector of the x-axis. 2) Determine the velocity of the boat after the man has dived. 3) Determine the work done by the man.
