Unformatted text preview: Chapter 9, Problem 51 A tennis ball, starting from rest, rolls down the hill in the figure. At the end of the hill the ball becomes airborne, leaving at an angle of 35° with respect to the ground. Treat the ball as a thinwalled spherical shell, and determine the range x . Chapter 9, Problem 56 Conceptual Example 14 provides useful background for this problem. A playground carousel is free to rotate about its center on frictionless bearings, and air resistance is negligible. The carousel itself (without riders) has a moment of inertia of 139 kg∙m 2 . When one person is standing at a distance of 1.48 m from the center, the carousel has an angular velocity of 0.633 rad/s. However, as this person moves inward to a point located 0.533 m from the center, the angular velocity increases to 0.757 rad/s. What is the person's mass? Number Units Chapter 10, Problem 16...
