A horizontal 925 N merry-go-round of radius 1.91 m is started from rest by a constant horizontal force of 51.7 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/s. Assume the merry-go-round is a solid cylinder.
Answer in units of J.
