A 2-kg solid sphere and a 2-kg solid cylinder are held at rest 5-m up an incline of 42 degrees.Both have a radius of 0.125-m. Assuming that the sphere and the cylinder roll down the incline without slipping, what speed will they have upon reaching the bottom of the incline. I(solid sphere)=(2/5)mr^2 I(solid cylinder)=(1/2)mr^2.
