A car initially traveling at 27.2 m/s undergoes a constant negative acceleration of magnitude 1.90 m/s2 after its brakes are applied. (a) How many revolutions does each tire make before the car comes to a stop, assuming the car does not skid and the tires have radii of 0.325 m

Therefore, the revolutions that each tire makes is:

Explanation:

We can use the following equation:

(1)

The angular acceleration is:

and the initial angular velocity is:

Now, using equation (1) we can find the revolutions of the tire.

Therefore, the revolutions that each tire makes is:
