A car initially traveling at 25.7 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 0.320 m?
________ rev
(b) What is the angular speed of the wheels when the car has
traveled half the total distance?
________rad/s
