Question

2a A 20 kg and 0 6 meter radius sphere was released from rest on a 30 degree ramp. The friction was 2 2 N Find the angular acceteration. Provide a free body diagram and indicate the plvot-center-o.AmR and I-rim-1.4 mRR Find the angular velocity after 5 sec Find the linear acceleration Find the linear velocity after 5 sec 2b After S sec sliding and rolling down the 30-degree ramp, an exchange impulse of to be delivered to the sphere center of mass due to a collision with a 9-kg cube sliding Find the ang the same direction after the collision? at 0.5 m/s ular velocity of the sphere immediately after the collision. Would the rolling still continue in Find the rolling speed immediately after collision Find the linear velocity of the sphere immediately after the collision. Find the velocity of the cube immediately after the collision. What would be the exchange impulse if the sphere and cube shared the same linear velocity immediately after the collision? (hint: moving together totally inelastic collision) r be Since the cube had higher acceleration when compared to the sphere, could the moving togethe observed? I Fa
