(Answered) A sphere of mass 100 kg and radius 025 m i r2 is rolling

Academics

A sphere of mass 10.0 kg and radius 0.25 m (I= R2 ) is rolling and its translational speed is 5.0 mjs. The sphere encounters a dip inclined at 30° to the horizontal and which is 15.0 m long (see figure). What is the speed of the sphere at the bottom of the dip?
