During a very quick stop, a car decelerates at 7.00 m/s2. What is the angular acceleration of its 0.280-m-radius tires, assuming they do not slip on the pavement? How many revolutions do the tires make before coming to rest, given their initial angular velocity is 95.0 rad/s ? How long does the car take to stop completely? What distance does the car travel in this time? What was the car’s initial velocity? Do the values obtained seem reasonable, considering that this stop happens very quickly?

Question

During a very quick stop, a car decelerates at 7.00 m/s2.      What is the angular acceleration of its 0.280-m-radius tires, assuming they do not slip on the pavement?      How many revolutions do the tires make before coming to rest, given their initial angular velocity is 95.0 rad/s ?      How long does the car take to stop completely?      What distance does the car travel in this time?      What was the car’s initial velocity?      Do the values obtained seem reasonable, considering that this stop happens very quickly?

anonymous · Answer

angular acceleration is 0.196 radians per second squared and and number of revolutions is  may be 13.48 . the distance travelled by the car is 13.155m. initial velocity is 13.57m/s
