(a)
Calculate the force (in N) needed to bring a 1000 kgcar to rest from a speed of 80.0 km/h in a distanceof 100 m (a fairly typical distance for a non-panicstop).
N
(b)
Suppose instead the car hits a concrete abutment at full speedand is brought to a stop in 2.00 m. Calculate the forceexerted on the car and compare it with the force found in part(a).
