A) Estimate the rotational inertia of a 60-kg ice skater by considering her body to be a cylinder. Assume she's holding her arms tight to her torso, so they don't contribute significantly to her rotational inertia. Suppose that the distance from the center of rotation to the shoulders is 0.2 mm. B) Estimate the rotational inertia if she extends her arms fully. Suppose that the arm span of the ice skater is 1.6 mm and the arms make up 15...

A yo-yo has a rotational inertia of 900 g · cm2 and a mass of 100 g. Its axle radius is 3.2 mm, and its string is 120 cm long. The yo-yo rolls from rest down to the end of the string. (a) What is the magnitude of its linear acceleration? (b) How long does it take to reach the end of the string? As it reaches the end of the string, what are its (c) linear speed, (d) translational...

True/False: Gravity is an example of inverse square behavior. A grindstone is rotating at constant rotational speed. There is a net torque on it. A lever multiplies a force but does not redirect it. On a rotating merry go round one child sits halfway out between the axis and the edge. Another child sits on the edge. Both kids have the same rotational speed. Angular momentum is a vector.

Write True or False. If False, rewrite the statement as a true. 9. When a collision occurs between two objects, the vector sum of the momenta changes. 10. All collisions conserve momentum and can be distinguished on the basis of whether they also conserve kinetic energy. 11. During a hockey game, a stationary goalie stops a puck. If we know his kinetic energy after the save, we can determine the initial kinetic energy of the puck. 12. When two bodies...
