(a) Calcuiate the force (in N) needed to bring a 553 kg car tn rest from a speed of 80.0 kmfh in a distance of 105 rh (a fairly typicai distahte for a non-panit Stop). 71714 x N (b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Caicuiate the force exerted on the car and compare it with the force found in part (a). L\" \"'i =|:l force in (a)
