Physics

A compost barrel can be considered as a solid cylinder of mass50.0 kg and radius of r = 30.0 cm, and a length of 0.900 m. It canbe turned about the long axis by applying a force to a handlelocated d = 20.0 cm from the axis of the cylinder. The compostbarrel needs to be turned through 250 complete revolutions. Assumeyou can apply a constant force of F = 10.0 N (always perpendicularto the radius as the handle goes around in a circle).
What is the angular acceleration of the barrel?
How much time does it take to turn the barrel through 250rev?
What is the angular velocity of the barrel at the end of that time?Is this reasonable?
