Question

A 16 kg child is spinning while holding their favorite toy (toy mass is 1
kg). If the child's arms are 24 cm in length, by how much does the
child's moment of inertia change when their arms are stretched out
(with the toy) as compared to when they are pulled in? Assume the
closest the child's arms can come to their center of rotation is 10 cm
and that each arm is about 1 kg in mass (the mass of the arms is
included in the 16 kg.)

A thin empty frame is hung along side A (see figure). Side A is 1.08 m long and side B is 0.9446 m long. Side C is hit by a bullet with a mass of 21.51 g, an initial speed of 188.825 m/s and a final speed of −113,566 m/s. Calculate the rotational speed of the frame after the ball has bounced against it if the frame rotates frictionlessly about the z-axis and the mass moment of inertia of the frame around this axis is 1,563 kg · m². Assume that the ball bounces straight back after the impact.

A 60-g steel sphere attached to a 200-mm cord can swing about point O in a vertical plane. It is subjected to its own weight and to a force F exerted by a small magnet embedded in the ground.The magnitude of that force expressed in newtons is F= 3000/r2 , where r is the distance from the magnet to the sphere expressed in millimeters. Knowing that the sphere is released from rest at A , determine its speed as it passes through point B.
