1. The problem statement, all variables and given/known data The velocity of a particle is related to its position by: v2 = w2 (A2 - x2) where w and A are constants. Show that the acceleration is given by: a=-w2x 2. Relevant equations 3. The attempt at a solution a= v* dv/dt v=(A2w2-x2w2)1/2 dv/dt= 1/2 (A2w2-x2w2)-1/2 * -2xw2 v * dv/dt = 1/2*-2xw2 * (A2w2-x2w2)1/2/ (A2w2-x2w2)-1/2 -w2x I think this is the proper way of showing the acceleration, but I'm not 100% with my chain rule and cancellations.
