Question

In the figure, an 66kg man is on a ladder hanging from a balloon that has a total mass of 400kg (including the basket passenger). The balloon is initially stationary relative to the ground. If the man on the ladder begins to climb at 1.2m/s relative to the ladder, (a) in what direction does the balloon move? (b) At what speed (with respect to the ground) does the balloon move? (c) If the man stops climbing, what is the speed of the balloon?
