Name__________________________________ Angular Motion II Per_______

A disk is rotating at a constant 60 R.P.M. Point P sits 6 cm from the center. The disk now starts to decelerate at 1 rad/s/s.

1)

What is the disk’s angular velocity before decelerating? (rad/s)

2)

What was Point P’s linear velocity before decelerating? (m/s)

3)

How much time will the disk need to stop? (sec)

4)

What is the disk’s angular displacement during deceleration? (rads)

5)

What is the disk’s linear displacement during deceleration? (m)
