A child is standing on the edge of a merry-go-round, 1.5 m from the center. At t = 0 the child has a linear speed of 8.0 m/s. 12 seconds later the ride has slowed down and the child’s speed is now 3.0 m/s. What are the: a) Angular Acceleration b) Radial Acceleration at t = 12s c) Tangential Acceleration d) Magnitude of the Total Acceleration at t = 12s
