A merry-go-round is stationary. A dog is running on the ground just outside its circumference, moving with a constant angular speed of 0.705 rad/s. The dog does not change his pace when he sees what he has been looking for: a bone resting on the merry-go-round one third of a revolution in front of him. At the instant the dog sees the bone (t = 0), the merry-go-round begins to move in the direction the dog is running, with a constant angular acceleration of 0.0160 rad/s2.
(a) Determine at what time will the dog reach the bone?

(b) The confused dog keeps running and passes the bone. Find how long after the merry-go-round starts to turn do the dog and the bone draw even with each other for the second time?
