A cylinder with a radius of 0.5 m and mass of 2.0 kg rolls down a frictionless ramp from a height of 3.6 m. At the very bottom of the ramp, it collides with, and sticks to, a 5.0 kg mass (i.e., it is a perfectly inelastic collision). This combined object now slides along the flat floor, where the coefficient of kinetic friction is 0.56. How far does the combined object travel along the floor before coming to a stop?

Two identical tops, #1 and #2, spin with angular velocities ω1 = 10 rad/s counterclockwise and ω2 = 12 rad/s clockwise. The tops bump into one another and separate. After the collision, the first top has angular velocity of 5 rad/s counterclockwise. During the collision, the force of impact is along the line connecting the centers of the top, so no torque is exerted on either top. What is the magnitude of the angular velocity of the second top? Does the top spin clockwise or counterclockwise?
