A constant force of 50.0 N is applied tangentially to the outer edge of a merry-go-round. The following diagram shows the view from above.
The merry-go-round has a moment of inertia of 450 kg m2 about a vertical axis. The merry-go-round has a diameter of 4.00 m.
The merry-go-round starts from rest and the force is applied for one complete revolution.
Calculate, for the merry-go-round after one revolution, the angular speed.
