[SOLVED] Physics - power and motion 1. The problem statement, all variables and given/known data A body is moving in a straight line under the influence of a source of constant power. Show that its displacement in time t is proportional to t3/2 2. Relevant equations P = F.v F = dp/dt, p=mv v = dx/dt 3. The attempt at a solution Absolutely no idea where to begin, sorry. I'm not even sure what 'source of constant power' means here - is the force constant or the velocity?
