A girl stands on the edge of a merry-go-round of radius 1.90 m. The merry-go-round is then uniformly accelerated from rest to its final speed of 2.99 rad/s in 13.5 s. How many revolutions does the merry-go-round make while getting up to speed?

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,...
