A turntable that spins at a constant 80.0 rpm takes 3.80 s to reach this angular speed after it is turned on. Find its angular acceleration (in rad/s'), assuming it to be constant, and the number of degrees it turns through while speeding up. Express your answer in radians per second squared.

A centrifuge in a forensics laboratory rotates at an angular speed of 3,750 rev/min. When switched off, it rotates 54.0 times before coming to rest. Find the constant angular acceleration of the centrifuge (in rad/s). Consider the direction of the initial angular velocity to be the positive direction, and include the appropriate sign in your result. |rad/s2

As you drive down the road at 18 m/s, you press on the gas pedal and speed up with a uniform acceleration of 1.22 m/s² for 0.60 s. You may want to review (Page 312). If the tires on your car have a radius of 33 cm, what is their angular displacement during this period of acceleration? Express your answer using two significant figures.
