1. A hollow sphere (mass 2.75 kg, radius 19.9 cm) is rolling without slipping along a horizontal surface, so its center of mass is moving at speed v_o. It now comes to an incline that makes an angle 25.6^o with the horizontal, and it rolls without slipping up the incline until it comes to a complete stop. Find a, the magnitude of the linear acceleration of the ball as it travels up the incline, in m/s².

2. At t = 0, a hollow sphere (mass 2.85 kg, radius 27.8 cm) moving at v_o = 24.6 m/s comes to an incline that makes an angle 36.1^o with the horizontal, If the sphere rolls without slipping up the incline: how long will it take, in seconds, for the sphere to come to a complete stop.t

A thin-walled hollow cylinder with mass m1 and radius R1 rolls without slipping on the inner wall of a larger thin-walled hollow cylinder with mass m2 and radius R2 >> R1. Both cylinders' axes are aligned and horizontal, and some magical mechanism ensures this perfect friction contact between them. Unfortunately for you, the larger cylinder rolls without slipping on a horizontal surface. Describe the motion including small oscillation frequencies near any equilibria if the systems is released from rest with...

A sphere of radius 2.09 cm and a spherical shell of radius 6.97 cm are rolling without slipping along the same floor. The two objects have the same mass. If they are to have the same total kinetic energy, what should the ratio of the sphere\'s angular speed to the spherical shell\'s angular speed be? Please provide a clear explanation. I have tried to look this problem u, but I was unable to understand exactly how the solution was found.

A hollow sphere of mass M and radius R is hit by a pendulum of mass m and length L that is raised at an angle θ. After the collision the pendulum comes to a stop and the sphere rolls forward into a spring with stiffness k on an incline of ϕ. Find an expression for how far ∆x the spring compresses along the incline. Use only m, L, M, R, θ, ϕ, k and appropriate constants.
