An automatic dryer spins wet clothes at an angular speed of 5.9 rad/s. Starting from an initial angular speed of 1.9 rad/s, the dryer reaches its operating speed with an average angular acceleration of 4.0 rad/s squared. How long does it take the dryer to come up to the normal operating speed of 5.9 rad/s? What is the angular displacement for this period of time?
