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....
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
