1. The problem statement, all variables and given/known data Object A of mass m is pushed with a constant force, another object B of the same mass is pushed with a force that does work at constant rate. Velocity of both objects increase from v to 2v and they move a distance of s. Find the ratio of the time taken by objects A and B to move the distance s 2. Relevant equations 3. The attempt at a solution Firstly, for object A s = 1/2(v + 2v)t t = 2s/3v Object B has constant power, so change in energy = work done = 3/2 mv2 3/2 mv2 = Pt v = (2Pt/3m)1/2 integrating this term, i get s = 1/3 (8Pt3/9m)1/2 But how do i eliminate m and p?
