A uniform solid disk is rolling without slipping along a horizontal surface with a linear speed...
A uniform solid disk is rolling without slipping along a horizontal surface with a linear speed of 3.60 m/s when it starts going up a ramp that makes an angle of 31.0o with the horizontal. What is the speed of the disk after it has rolled 1.75 m up the ramp (the 1.75 m is the distance along the ramp)? Make sure you show any appropriate diagrams and all of your work. SHOW ALL WORK

A hollow sphere (mass 8.8 kg, radius 54.8 cm) is rolling without slipping along a horizontal surface, so its center of mass is moving at speed vo. It now comes to an incline that makes an angle 56o 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.

A glider is free to move along an air track, which is raised at an angle of 45° above a horizontal tabletop. The glider is first placed at the top of the track so that it is at a height h above the tabletop, and after being released, it reaches a speed v at the bottom of the track. Assuming friction acts on the glider during its motion, which of the following statements is(are) true when the glider has reached...
