Transcribed Image Text:

A child, hunting for his favorite wooden horse, is running on the ground around the edge of a stationary merry-go-round. The angular speed of the child has a constant value of 0.222 rad/s. At the instant the child spots the horse, one-quarter of a turn away, the merry- go-round begins to move (in the direction the child is running) with a constant angular acceleration of 0.0132 rad/s2. What is the shortest time it takes for the child to catch up with the horse?
