Homework Help: physics

Posted by brooke on Thursday, June 21, 2012 at 12:47am.

A dad pushes tangentially on a small hand-driven merry-go-round and is able to accelerate it from rest to a frequency of 16 rpm in 11.5 s. Assume the merry-go-round is a uniform disk of radius 3.0 m and has a mass of 790 kg, and two children (each with a mass of 25 kg) sit opposite each other on the edge. 1)Calculate the torque required to produce the acceleration, neglecting frictional torque. 2)What force is required at the edge? I got 1400 for the force and it was wrong.
