A little boy jumps onto a small merry-go-round
(radius of 2.00 m) in a park and rotates for 2.30 s through
an arc length distance of 2.55 m before coming to rest. If
he landed (and stayed) at a distance of 1.75 m from the
central axis of rotation of the merry-go-round, what was
his average angular speed and average tangential speed?

A playground merry-go-round has a moment of inertia of 600 kg m2. When the merry-go-round is at rest, a 20 kg boy runs at 5.9 m/s along a line tangential to the rim and jumps on, landing on the rim a distance of 3.0 m from the rotation axis of the merry-go-round. The angular velocity of the merry-go-round is then: A.1.2 rad/s B.0.38 rad/s C.0.45 rad/s D.0.56 rad/s E.0.72 rad/s

A 20-kg child running at 2.0 m/s jumps onto a playground merry-go-round that has inertia 180 kg and radius 1.6 m. She is moving tangent to the platform when she jumps, and she lands right on the edge. Ignore any friction in the axle about which the platform rotates. What is the rotational speed of the merry-go-round and the child if the merry-go-round started from rest? Express your answer with the appropriate units.

A merry-go-round (radius = 4 m) with a perfect frictionless bearing is pushed with a force of 24 N by a young girl. She pushes with a constant force that is oriented tangentially to the edge of the merry-go-round. After she pushes the merry-go-round through 14 full rotations (at which point she lets go) it is spinning with an angular speed of 3 rad/s. a) What is the moment of inertia of the merry-go-round? b) After the girl lets go,...
