I = mi ri^2 =(150)(0.2)^2 = 6 kg m2 KE= 1/2 I w^2 =(0.5)(6)(50)^2 =7500 J um...where do I fit this into what I did above? Was all my steps above required to the question?

1. A solid sphere has a radius of 0.200 m and a mass of 150 kg. How much work is required to get the sphere rolling with an angular speed of 50.0 rad/s on a horizontal surface? Assume the sphere starts from rest and rolls without slipping 2. The attempt at a solution I found V first. V= rw =...
