(a) Calculate the force needed to bring a 1005.0-kg car to rest from a speed of 100.0 km/h in a distance of 47.0-m (a fairly typical distance for a non-panic stop). Newtons (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. Newtons Check
