Motion with changing mass
1. The problem statement, all variables and given/known data
2. Relevant equations
3. The attempt at a solution
It seems part b is trivial. Obviously, the propellsion force is constant. To find F, just subs m=m/2
I am not sure wheather I am right.

Why should the propulsion force be constant? As the water level goes down the water pressure at the bottom of the bucket will be lower so the water velocity will be less?
