A horizontal 873 N merrygoround of radius 1.11 m is started from rest by a constant horizontal force of 70.6 N applied tangentially to the merrygoround. Find the kinetic energy of the merrygoround after 3.59 s. The acceleration of gravity is 9.8 m/s2 . Assume the merrygo round is a solid cylinder.
Answer in units of J.

is 721.12 ... use KE=(((F*t)^2)g)/W W= 873, F=70.6 t=3.59, g=9.8
