1. The problem statement, all variables and given/known data A solid sphere of uniform density (weight = 3.2 lbs starts from rest and rolls down a ramp (H = 1.57 m, q = 18.3°.) Find the speed of the sphere's CM when it reaches the bottom of the ramp. haha sorry bout that.... 2. Relevant equations see below 3. The attempt at a solution i dont' know whats wrong with my set up here, m*g*d*sin(theta) = .5mv^2 + (2/5)(.5)mv^2 any help? thanks!
