Problem:

A car initially traveling at 29.2 m/s undergoes a constant negative acceleration of magnitude 1.40 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  0.305 m.

NOTE:  Answer of  (a) must differs from the correct answer by more than10%.

(b) What is the angular speed of the wheels when the car has traveled half the total distance?

NOTE:  Answer of  (b) must differs from the correct answer by more than10%.
