The angular velocity of a process control motor is (10−1/2t^2) rad/s, where t is in seconds.
a. At what time does the motor reverse direction?
I got 4.5 s which is correct
b. Through what angle does the motor turn between t =0 s and the instant at which it reverses direction?
I do not know how to solve part b
