SUMMARY
The average crush force exerted on a car can be calculated using the formula Average Crush Force = mv² / 2d, where m represents the mass of the car in kilograms, v is its velocity in meters per second, and d is the distance over which the force is applied. This relationship is derived from the kinetic energy equation, Ke = (1/2)(mv²), indicating that all kinetic energy is converted into work during the crushing process. The work done on the object can be expressed as W = Fd, confirming the validity of the average crush force formula.
