(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A horizontal 800N merry go round of radius 1.50m is started from rest by a constant horizontal force of 50.0N applied tangetially to the merry go round. Find the kinetic energy of the merry go round after 3.00s. (assume it is a solid cylinder).

2. Relevant equations

I = MR^2

KE (rotational) = I (omega)^2

3. The attempt at a solution

I know this is a straight forward question. I don't know where to start. I know there are a few unknowns: omega, angular acceleration, velocity.

can someone guide me please? thanks
