An incline plane of height h and angle theta. At the top of the incline are two objects: a solid sphere and a solid cylinder. Both are labeled with mass M and radius R. Arrows indicate they are starting from rest and will roll down the slope.
Solid sphere and cylinder on an incline.
A uniform solid sphere and a uniform solid cylinder, both of mass \(M\) and radius \(R\), are released from rest at the top of an incline of height \(h\). Both objects roll down the incline without slipping. What is the ratio of the translational kinetic energy of the sphere to the translational kinetic energy of the cylinder when they reach the bottom of the incline?
