(a) Calculate the force needed to bring a 950 kg car to rest from a speed of 90.0 km/h in a distance of 110 m (a fairly typical distance for a nonpanic stop). (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.
