The gear shown has a radius R=150mm and a radius of gyration k =125mm. The gear is rolling without sliding with a velocity V1 of magnitude 3 m/s when it strikes a step of height h=75mm. Because the edge of the step engages the gear teeth, no slipping occurs between the gear and the step. Assuming perfectly plastic impact, determine the angular velocity of the gear after it has rotated to the top of the step.
