A 925-kg pickup decelerates to rest from a speed of 75 km/h in a distance of 140 m. Consider that the pickup is initially moving in the positive direction. Suppose instead of braking that the pickup hits a concrete abutment at frill speed and is brought to a stop in 2.00 m. Calculate the force, in newtons, exerted on the pickup in this case. What is the ratio of the force on the pickup fr om the concrete to the braking force?
