A motorized wheel is spinning with a rotational velocity of wo = 1.65 rad/s. At t = 0 s, the operator switches the wheel to a higher speed setting. The rotational velocity of the wheel at all subsequent times is given by w(t) = wo tan¯¹ (c + bt²) where c 1.5574 and b = 6.97 s². At what time ta,max in milliseconds is the rotational acceleration at a maximum? What is the maximum tangential acceleration at,max of a point on the wheel a distance R = 1.17 m from its center? What is the magnitude a of the total linear acceleration when tangential acceleration is a maximum? 0.383 ta,max ms Incorrect at,max= 1.39 m/s² 7.948 a = m/s² Incorrect
