A sphere of radius r starts from rest and rolls without slipping along a curved surface, dropping through a vertical distance of 0.431 m. Find the final speed v of the sphere's center of mass.
Homework Answers
Energy conservation
Potential energy = rolling kinetic energy + translation kinetic energy
mgh= 1/2mv^2 + 1/2 I *w^2
I=2/5 *mr^2 , w=v/r
0.7v^2= 9.81*0.431, v= 2.46 m/s

A sphere of mass M and radius R starts at rest and rolls without slipping down an incline and embeds itself in a hollow cube at the bottom that is only 1/5 its mass. If the incline is h tall and the table has a height of D from the floor, at what horizontal distance from the table do the two objects land? The cube/sphere combination leaves the incline moving horizontally.
