QUESTION 10 A merry-go-round starts from rest and undergoes an angular acceleration of 1 rad/s-for 30 seconds. Then, the merry-go-round is slowed down by applying the brakes, which applies an angular acceleration of -0.5 rad/s for a total time of 10 seconds, What is the final angular velocity of the merry-go-round? Write your answer down in units of radians per second (rad/s), but only write down the number part of you
