An electric saw uses a circular spinning blade to slice through wood. When you start the saw, the motor needs 6 seconds of constant angular acceleration to bring the blade to its full angular velocity. If you change the blade so that the rotating portion of the saw now has 5 times its original rotational mass, how long will the motor need to bring the blade to its full angular velocity?
