A car initially traveling at 29.0 m/s undergoes a constant negative acceleration of magnitude 1.75 m/s^2 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 a radii of 0.330 m? (b) What is the angular speed of the wheels when the car has traveled half the total distance?
