You are on the edge of a merry-go-round that has a moment of
Inertia IM, radius R, and an initial angular speed of ωo spinning
in the cw direction. You may take your mass as Mu. Beside you is a
pile of 5 snowballs each of mass ms. You will throw each of these
tangentially (such that your location on the Merry-GoRound is their
point of closest approach during their trajectories) with speed v
in the direction needed to speed up the Merry-Go-Round. What is the
angular speed of the Merry-goround after throwing all 5
snowballs?

Starting at rest, a child applies a 63N force tangent to the edge of a merry-go-round through 31 2 rotations. At that moment, she stops and admires her spinning merry-go-round. Then she jumps onto the edge of the merry-go-round. The girl’s mass is 25kg, the merry-go-round’s moment of inertia is 70kg· m2, and the merrygo-round’s diameter is 2.0m. What is the ﬁnal angular speed of the girl and merry-go-round? Child applies tangential force. Fan
A playground merry-go-round of radius R = 2.10 m has a moment of inertia of I = 260 kgm2 and is rotating at 11.0 rev/min about a frictionless vertical axis. Facing the axle, a 23.0 kg child hops on to the merry-go-round and manages to sit down on its edge. What is the new angular speed of the merry-go-round?
A 90-kg merry-go-round of radius 2.0 m is spinning at a constant speed of 20 revolutions per minute. A kid standing on the ground decides to bring the merry-go-round to rest and applies a force of 10.0 N tangentially to the merry-go-round. If the merry-go-round is modelled as a solid cylinder, (A) calculate its moment of inertia. (B) What is the angular acceleration of the merry-go-round? (C) How many revolutions will the merry-go-round complete until it finally stops? 1) [25...
