A roundabout is a type of playground equipment involving a large
at metal disk that is able to spin about its center axis. A
roundabout of mass 120kg has a radius of 1.0m is initially at rest.
A child of mass 43kg is running toward the edge of the roundabout
(meaning, running on a path tangent to the edge) at 2.7 m/s and
jumps on. Once she jumps on the roundabout, they move together as a
single object. Assume the roundabout is a uniform disk.
1. What is the magnitude of her angular momentum (with respect to
the center of the roundabout) just before she jumps?
2. What is the angular speed of the roundabout after the
jump?
3. Does the overall kinetic energy of the system increase,
decrease, or remain constant? If you say it changed, explain what
caused a change in energy.

(4) A playground ride, known as merry-go-round, consists of a disk with a mass of 40.0 kg and a radius of 1.80 m mounted on a frictionless axle. The frictionless axle is a vertical cylinder of radius kg, and has the same rotational axis as the disk. A child with a mass of 3.50 m/s on a line tangential to the outer rim of the disk and jumps onto the outer edge of the ride while it is at rest...

A merry-go-round modeled as a disk of mass 100 kg and radius 2.0 m is rotating around a frictionless vertical axle. After a person of mass 60 kg jumps onto the merry-go-round, the system’s angular speed decreases to 2.0 rad/s. If the person walks slowly from the edge toward the center, find the change in the system’s rotational kinetic energy caused by her movement to 0.5 m from the center.

A merry-go-round is a common piece of playground equipment. A 2.8-m-diameter merry-go-round with a mass of 260 kg is spinning at 22 rpm. John runs tangent to the merry-go-round at 5.0 m/s, in the same direction that it is turning, and jumps onto the outer edge. John's mass is 39 kg. What is the merry-go-round's angular velocity, in rpm, after John jumps on?
