    The angular velocity of a process control motor is (21−(1/2t^2)) rad/s

    oh ok, so I just integrate the function then?, If I integrate it then I get (21t - (1/6t^3) + c), what do i do with the constant c though?

    ok, I'll integrate the function

    The angular velocity of a process control motor is (21−(1/2t^2)) rad/s

    Homework Statement The angular velocity of a process control motor is (21−(1/2t^2)) rad/s, where t is in seconds. 1.) At what time does the motor reverse direction? 2.) Through what angle does the motor turn between t =0 s and the instant at which it reverses direction? Homework Equations...
