A hollow ball and a solid sphere are released from rest and roll down an inclined plane. Both have a mass of 1 kg, a radius of 5 cm, and experience a torque of 0.01 N m. Assume both balls roll without slipping. What is the difference in their linear velocities after the balls have both lost 4 m of elevation? I’d like you to use energy to solve this problem.

Rotational Inertia –Rolling Kinetic Energy. A solid sphere, a hollow sphere, a hollow cylinder, and a solid cylinder, all of with same mass (M=0.25 kg ) and radius(R= 0.20 m) – are placed at the top of an incline at height (h= 1.5 m ). All the objects are released from rest at the same moment to roll down without slipping. Hint: search for the rotational inertia formula for each of the rolling object first. Then calculate each of them...

A solid sphere, a follow sphere, and a ring (a hollow cylinder) of uniform density, each with radius 0.24m and mass 2.6kg roll without slipping on a flat surface at an angular speed of 6.1 rad/s. They then roll without slipping up an incline. 1. What is the linear speed of the center of mass of the ring when it is rolling on the flat surface? 2. What happens as the objects roll up the incline? 3. How high up...
