Car crash force from seat belt. A car crashes head on into a wall and stops, with the front collapsing by 0.500 m. The 75 kg driver is firmly held to the seat by a seat belt and thus moves forward by 0.500 m during the crash. Assume that the force on the driver from the seat belt is constant during the crash. Use the work-kinetic energy theorem to find the magnitude of that force during the crash if the initial speed of the car is (a) 40 mi/h and (b) 80 mi/h? (c) If the initial speed is multiplied by 2, as here, by what multiplying factor is the force increased? (a) Number (b) Number i (c) Number Units Units Units Car crash force from seat belt.
