A car moving on the road stops suddenly, and the car speed gets decelerated at 7.00 m/s2.
(a) If the radius of the tires is 0.280m, find the angular acceleration, assuming they do not slip on the walkway.
(b)Before coming to rest, how many revolutions do the tires make? (If the initial velocity is 95 rad/s)
(c) Calculate the time required by the car to stop completely.
(d) Calculate the distance traveled by car at this time.
(e) Find the initial velocity of the car.
(f) Analyze the values obtained? Does it seem reasonable, if this stop happens very quickly?
