Abicycle tire is spinning counterclockwise at 2.70 rad/s. during a time period at 1.90 s, the tire is stopped and spun in the opposite (clockwise) direction also at 2.70 rad/s. calculate the change in the tire's angular velocity aw and the tire's average angular acceleration aav. (indicate the direction with the signs of your answers.)
(a) the change in the tire's angular velocity aco (in rad/s) rad/s
(b) the tire's average angular acceleration aav (in rad/s2) rad/s
