An automatic dryer spins wet clothes at an angular speed of 4.4 rad/s. Starting from rest, the dryer reaches its operating speed with an average angular acceleration of 4.2 rad/s2. How long does it take the dryer to come up to speed?

  • physics -

    V = Vo + at = 4.4 rad/s.
    0 + 4.2t = 4.4
    t = 4.4/4.2 = 1.05 s.
