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
