An automobile tire is rated to last 50000 miles.to an order magnitude, through how many revolutions will it turn ?

An object travels in a circular path. It takes 2.4 seconds to complete each rotation. If the radius of the circle is 6.3 m, what is the object's average linear speed?

A speed skater increases her speed form 10 m/s to 12.5 m/s over a period of 3 seconds while coming out of a curve of 20 m radius. What are the magnitudes of her radial, tangential and total accelerations as she leaves the curve?

What is the magnitude of the Earth’s centripetal acceleration?

A car travels at a constant speed around a circular track whose radius is 2.67 km. The car goes once around the track in 285 s. What is the magnitude of the centripetal acceleration of the car?

In a circular motion, if an object has a speed of 34.8m/s, and radius of the circular path is 80.2 m, what is the centripetal acceleration in m/s2?

A fairground ride spins its occupants inside a flying saucer-shaped container. If the horizontal circular path the riders follow has a 4.8 m diameter, if the riders is subjected to a centripetal acceleration 1.3 times that due to gravity, what is the spinning speed in unit of revolutions per minute? Use g = 9.8 m/s2.

The tires of a car make 82 revolutions as the car reduces its speed uniformly from 96 km/h to 63 km/h. The tires have a diameter of 0.70 m. If the car continues to decelerate at this rate; how much more time is required for it to stop? (Your result must be in seconds and include 1 digit after the decimal point. Maximum of 2% of error is accepted in your answer.)
