Learning Goal: To apply the principle of angular impulse and momentum to find final speed and the time to reach a given speed. M B As shown, ball B, having a mass of 10.0 kg, is attached to the end of a rod whose mass can be neglected. Part A - Finding the final speed of the ball If the rod is 0.550 m long and subjected to a torque M = (2.45t² + 4.45) N-m, where t is in seconds, determine the speed of the ball when t= 3.10 s. The ball has a speed of v = 2.80 m/s when t = 0. Express your answer to three significant figures and include the appropriate units.

The rotation axis of the uniform cylinder is constrained by a frictionless slot. The cylinder is at rest when it is lowered onto the conveyor belt, which has a constant translational velocity of 20.0 ft/s. The coefficient of friction between the belt and the cylinder is 0.400.a) Calculate the maximum angular velocity of the cylinder.b) The distance traveled by the belt during the time the cylinder is accelerating to its maximum angular velocity
