6 - Kinetic Energy and the Work-Energy Theorem Points: 20 Calculate the force needed to bring a 930-kg car to rest from a speed of \( 94.0 \mathrm{~km} / \mathrm{h} \) in a distance of \( 118 \mathrm{~m} \) (a fairly typical distance for a non-panic stop). \[ -2.69 \times 10^{3} \mathrm{~N} \] You are correct. Your receipt no. is 163-4394 (2) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in \( 1.90 \mathrm{~m} \). Calculate the force exerted on the car and compare it with the force found in part (a). Force = Ratio \( = \)
