a) James with a mass of 60 kg stands at one end of a boat on still water. The boat has a length l = 3 m and mass m = 300 kg. Both James and the boat are initially at rest. James walks to the other end of the boat. Ignore the effect of water resistance. Find the displacement of the boat. (b) A rocket carrying a satellite arrives at the destination in space with initial velocity v0. Then the rocket separates with the satellite and continues to move along the SAME direction with velocity v1. The mass of the rocket and satellite are m1 and m2, respectively. Ignore the effect of air resistance. Find the final velocity of the satellite v2.
