During a very quick stop, a car decelerates at 7.05 m/s2. (a) what is the angular acceleration (in rad/s2) of its 0.270 m radius tires, assuming they do not slip on the pavement? (indicate the direction with the sign of your answer. assume the tires initially rotated in the positive direction.) -26.11 correct: your answer is correct. rad/s2 (b) how many revolutions do the tires make before coming to rest, given their initial angular velocity is 96.0 rad/s? 28 correct: your answer is correct. revolutions (c) how long (in s) does the car take to stop completely? 3.676 correct: your answer is correct. s (d) what distance (in m) does the car travel in this time? 95.11 incorrect: your answer is incorrect. m (e) what was the car's initial velocity (in m/s)? (indicate the direction with the sign of your answer.)
