(a) Calculate the force needed to bring a850kg car to rest from a speed of95.0km/h in a distance of110m (a fairly typical distance for a nonpanic stop). N (b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a), i.e. find the ratio of the force in part(b) to the force in part(a). (force in part (b) / force in part (a))
