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 vo. It now
comes to an incline that makes an angle 25.6o 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 =...
