Science Homework Help. Physics: Mechanical Energy
A horizontal 810-N merry-go-round of radius 1.70 m is started from rest by a constant horizontal force of 45 N applied tangentially to the merry-go-round. Find the kinetic energy of the merry-go-round after 4.0 s.
(Assume it is a solid cylinder. Also assume the force is applied at the outside edge.)
