A horizontal 700 N merry-go-round of radius 1.52 m is started from rest by a constant horizontal force of 42.9 N applied tangentially to the merry-go-round. Find the kinetic energy of the merry-go-round after 3.06 s. The acceleration of gravity is 9.8 m/s². Assume the merry-go-round is a solid cylinder.
