A large wooden turntable in the shape of a flat uniform disk has a radius of 2.00 m and a total mass of 140 kg . The turntable is initially rotating at 3.00 rad/s about a vertical axis through its center. Suddenly, a 80.0-kg parachutist makes a soft landing on the turntable at a point near the outer edge.
A. Find the angular speed of the turntable after the parachutist lands. (Assume that you can treat the parachutist as a particle.
B. Compute the kinetic energy of the system before the parachutist lands.
C. Compute the kinetic energy of the system after the parachutist lands.
D. Why are these kinetic energies not equal?

A turntable has a radius of 0.80 m and a moment of inertia of 2.0 kg m2. The turntable is rotating with an angular velocity of 1.5 rad/s about a vertical axis though its center on frictionless bearings.
A turntable has a radius of 0.80 m and a moment of inertia of 2.0 kg m2. The turntable is rotating with an angular velocity of 1.5 rad/s about a vertical axis though its center on frictionless bearings. A very small 0.40-kg ball is projected horizontally toward the turntable axis with a velocity of 3.0 m/s. The ball is caught by a very small and very light cup-shaped mechanism on the rim of the turntable (see figure). a) What is the...
A frictionless pulley has the shape of a uniform solid disk of mass 2.40 kg and radius 10 cm
A frictionless pulley has the shape of a uniform solid disk of mass 2.40 kg and radius 10 cm. A 1.20 kg stone is attached to a very light wire that is wrapped around the rim of the pulley (the figure ), and the system is released from rest. Part A How far must the stone fall so that the pulley has 4.80 J of kinetic energy? Part B What percent of the total kinetic energy does the pulley have?

A merry-go-round, which may be approximated as a solid disk of
mass 90.0 kg and radius 2.00 m, is originally at rest but free to
rotate in the horizontal plane about its center. A child applies an
external force of 20.0 N tangentially to the outer edge of the
merry-go-round, for a duration of 15.0 s.
(a) What is the final angular velocity of the merry-go-round?
(b) What is the average power supplied by the child in the

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.
