A car initially traveling at 29.0 m/s undergoes a con-stant negative acceleration of magnitude 1.75 m/safter its brakes are applied. (a) How many revolutionsdoes each tire make before the car comes to a stop,assuming the car does not skid and the tires have radiiof 0.330 m? (b) What is the angular speed of the wheelswhen the car has traveled half the total distance?12. A 45.0-cm diameter disk rotates with a constant angu-lar acceleration of 2.50 rad/s. It starts from rest at t=0, and a line drawn from the center of the disk to apoint Pon the rim of the disk makes an angle of 57.3find
