This girl is babysitting two 30-Kg kids at a neighborhood park. She places one on each end of a rotating ride that looks like a see-saw (but spins instead of going up and down). She pushes tangentially at one of those ends and is able to accelerate it from rest to 15-RPM in 10-s. The rotating ride is 3-m long, 30-cm wide and has a mass of 560-Kg. Calculate the torque required to produce the acceleration needed, neglecting frictional torque.
