1. The problem statement, all variables and given/known data A uniform, solid sphere of mass 350 grams and radius 25.0 cm has an axle attached to it tangent to its surface. The axle is oriented horizontally, causing the sphere to be suspended below it, its center of mass directly below the axle. Someone lifts the sphere until its center of mass is at the same vertical level as the axle. Upon releasing it, the sphere begins to rotate counterclockwise about the axle. ) Calculate the linear speed of a point on its outer edge (farthest from the axle) when the sphere’s center of mass returns to its position directly below the axle 2. Relevant equations Conservation of energy 3. The attempt at a solution I started off trying to use KEri + KEti + GPEi = KErf + KEtf + GPEf After substituting and eliminating I got to gh = 1/2Vf^2 + 1/4Vf^2 And then I got 2.55 m/s but according to the answer key, I should be getting 1.87 m/s. I not sure where I'm going wrong.
