A car crashes head on into a wall and stops, with the front collapsing by 0.584 m. The 65.0 kg driver is firmly held to the seat by a seat belt and thus moves forward by 0.584 m during the crash. Assume that the acceleration (or deceleration) is constant during the crash. What is its magnitude of the force on the driver from the seat belt during the crash if the initial speed of the car is (a) 35.0 mi/h and (b) 70.0 mi/h? (a) Number i Units (b) Number i Units w
