you are driving at a speed of 20 m/s. suddenly you see a deer 100m in front of the car and hit the brakes immediately. you are just able to save the deer. (a) calculate the acceleration. (b) how many seconds did you need to stop the car?

During a very quick stop, a car decelerates at 7.00 m/s2.

(a) What is the angular acceleration of its 0.280-m-radius tires, assuming they do not slip on the pavement?

(b) How many revolutions do the tires make before coming to rest, given their initial angular velocity is 95.0 rad/s?

(c) How long does the car take to stop completely?

(d) What distance does the car travel in this time?

(e) What was the car's initial velocity?

(f) Do the values obtained seem reasonable, considering that this stop happens very quickly?
