SUMMARY
The average force exerted on a car during a crash test is calculated to be 50613 N. This calculation is based on a car with a mass of 746.9 kg, an initial velocity of 36.8 m/s, and a final velocity of -20.8 m/s, with the collision duration lasting 0.85 seconds. The formula used is F * t = change in momentum, where the change in momentum is determined by the mass and the sum of the initial and final velocities.
