1. The problem statement, all variables and given/known data A penny is released from the top of a very smooth sphere of radius 1 m. The sphere is fixed to a platform and doesn't move. The penny slides down from rest and leaves the sphere at a certain point. How far will the penny fall away from the point of contact of the sphere and the platform? 2. Relevant equations (1) V = Vo + at (2) a = (V^2)/9.8 (3) V^2 = Vo^2 + 2a(x - xo) 3. The attempt at a solution Vo = 0 m/s r = 1 m a = g = 9.8 m/(s^2) x = ? => The distance the penny fell from the top of the sphere to ground. I used (1) in order to rearrange into t = V/g After doing that, I was thinking that maybe I could use (2) or (3) to rearrange the equation a little more to find the solution, but I'm sure that's not right, and I'm doing too much work. I've attached a pdf of the problem.
