A solid, uniform disk of mass 1.00 kg and radius .250m rotates with initial angular velocity of +26.3 rads/s about a frictionless vertical spindle through the center of the disk. A flat rectangular steel bar of mass 0.850 kg, length 0.400m, and width 0.050 M is dropped onto the disk so that the spindle passes through the center of the bar and is perpendicular to the plane of the bar. Assuming that there are no external torques on the system...

(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...

Problem 3: A merry-go-round can be considered a uniform disk of mass 145 kg and radius 2.10 m free to rotate about a frictionless axis through its center. A 40.0 kg child stands at the edge and the system is initially rotating at 0.300 rad/sec. The child begins to walk around the edge of the merry-go-round with a velocity of 0.250 m/s relative to the ground in the direction of the rotation. What is the angular velocity of the merry-go-round...

5. A 3.0 m diameter merry-go-round (mass 200 kg) is spinning at 10 rpm. A child of 30.0 kg runs tangent to the merry-go-round at 2.0 m/s, in the opposite direction that it is turning, and jumps onto the outer edge. Calculate the merry-go-round's angular velocity, immediately after the child jumps on.

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.

The mass of the disk is 0.35 kg with a radius of 0.18 m and is
initially spinning at 5 revolutions per second. It is spinning
horizontally and on a very low friction axle.
Then a uniform thin rod of length 0.40m and mass of 0.085 kg is
suspended just above the spinning disk and dropped, without any
rotational motion, onto the spinning disk exactly across its
diameter.
After the rod is dropped, the rod and disk are moving with...

A 70 kg merry-go-round disk has a radius of 3 meters and spins at 1.4 radians/sec with the 80 kg person on the edge. If the person moves so that they are now only 1 meter from the center, calculate the new angular speed of the merry-go-round system. Calculate the total kinetic energy of the system when the person is at the edge and when the person is at the 1 meter spot.
