a) (10p) You are in a small boat on a calm see. The mass of the boat is M-200 kg. Your mass is m-70 kg. You stand up, and make a step forward, with the velocity v of 1 m/s, as seen by an observer at rest on the coast. What would then be the recoil velocity V of the system made of the boat and yourself? Explain. b) (10 p) You jump from the boat with the same velocity in the sea. What will the be the recoil velcocity of the boat? a) (10p) You are in a small boat on a calm see.
