                Calculate the force needed to bring a 1100–kg car to rest from a speed of 83.0 km/h in a distance of 118 m (a fairly typical distance for a non-panic stop). Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 1.82 m. Calculate the force exerted on the car and compare it with the force found in part (a).

    In this case work takes away KE so
1/2 mv^2 = Fd (convert kph to m/s BTW)
Solve for F in both questions
