1. The problem statement, all variables and given/known data a) A bucket full of water is slid across a sheet of ice (no friction). As bucket fills (as it moving), what happens to its velocity and momentum? b) Now instead of filling the bucket with more water, say it has a leak as it moves, what happens to its velocity and momentum? 2. Relevant equations p=mv 3. The attempt at a solution a)The velocity decreases, but momentum is constant. I I do not see why this is the case. Is this because m = p/v, so if my mass is increasing v has to decrease. Momentum remain constant because pi = pf? b) Velocity constant, but momentum decreases. Here v = p/m. But I don't see the math behind why velocity is constant if you are losing mass (loss of mass means momentum decreases, since momentum is a factor of inertia).
