Question 1 10 pts A child on a merry-go-round takes 5.1 s to go around once. What is his angular displacement during a 2.5 s time interval? Assume uniform circular motion. Question 2 10 pts A rotating wheel requires 3.35 s to rotate 26.3 revolutions. Its angular velocity at the end of the 3.35 sec interval is 99 rad/s. What is the constant angular acceleration (in rad/s2) of the wheel
