Can I just plug in time? so 45 - (1/6)*4.5^3 = 29.81?

displacement = 10t-1/6t^3

velocity is the derivative of displacement

Multiply by time?

That was all that I was given. I am looking for the Delta theta

[moderator's note: Thread moved from forum General Physics, so no template shown] 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...
