Momentum...please help!! 1. The problem statement, all variables and given/known data A child of mass 31 kg sits on a wooden horse on a carousel. The wooden horse is 4.2 m from the center of the carousel, which rotates at a constant rate and completes one revolution every 6.7 seconds. What are the magnitude and direction of the perpendicular component of dp/dt for the child 2. Relevant equations p = mv 3. The attempt at a solution speed = d/t = 3.9 m/s p = mv = 31 kg*3.9 m/s = 12.09 kg*m/s But I don't know how to compute the components of dp/dt? I know the parallel component is 0 and has no direction, so what would the perpendicular one be? Thanks for the help!!!
