The differential gear of a car axle allows the wheel on the left side of a car to rotate at a different angular speed than the wheel on the right side. A car is driving at a constant speed around a circular track on level ground, completing each lap in 21.0 s. The distance between the tires on the left and right sides of the car is 1.00 m, and the radius of each wheel is 0.370 m. What is the difference between the angular speeds of the wheels on the left and right sides of the car? Number i Units

The tires of a car make 85.0. revolutions as the car reduces its speed uniformly from 90.0 km/hr to 60.0 km/hr. The tires have a diameter of 0.90 m. What is the angular acceleration? If the car continues to slow down at this rate, how much more time is required to stop?

A wheel of a radius 5.02 m rotates at a uniform speed. If a point on the rim of the wheel has a centripetal acceleration of 4.00 m/s2, what is the point’s tangential speed?

A 20 cm diameter circular saw blade spins at 3900 rpm. How fast would you have to push a straight hand saw to have the teeth move through the wood at the same rate as the circular saw teeth?

A centrifuge in a medical laboratory rotates at an angular speed of 3,800 rev/min. When switched off, it rotates through 52.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.

Some bacteria are propelled by motors that spin hair-like flagella. A typical bacterial motor turning at a constant angular velocity has a radius of 1.1 x10-8m, and a tangential speed at the rim of 2.4 x10-5 m/s.  How long does it take the motor to make one revolution?

A bus is traveling at a speed of 20.0 m on a straight horizontal road. The wheels have a radius of 0.400 m. If the bus speeds up with a linear acceleration of 1.50 m/s2 for 8.00 s, what is the angular speed of each of the wheels during this time?

The hard disk drive in a computer spins at a rate of 7.20 x 10^3 rpm. If the disk has a radius of 8.26 cm, what is the tangential speed of the outer edge of the disk?

An optical disk drive in your computer can spin a disk up to 10,000 rpm (about 1045 rad/s). If a particular disk is spun at 704.8 rad/s while it is being read, and then is allowed to come to rest over 0.502 seconds, what is the magnitude of the average angular acceleration of the disk? average angular acceleration: If the disk is 0.12 m in diameter, what is the magnitude of the tangential acceleration of a point 1/13 of the way out from the center of the disk? tangential acceleration: x10 TOOLS rad s² m

A centrifuge in a medical laboratory rotates at an angular speed of 3,550 rev/min. When switched off, it rotates through 54.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.
