Question (a) Calculate the force needed to bring a 900 style=”color:rgb(0,0,0);”> kg car to rest from a speed of 80.0 km/h in a distance of 125 m (a fairly typical distance for a nonpanic stop). Answer is in terms of 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))
