A set of crash tests consists of running a test vehicle moving at a speed of 12.4 m/s (27.7 mi/hr) into a solid wall. Strapped securely in an advanced seat belt system, a 57.0 kilogram (126lbs) dummy is found to move a distance of 0.720 meter from the moment the car touches the wall to the time the car is stopped. Compute the size of the average force which acts on the dummy during that time. Using the direction of motion as the positive direction, compute the average acceleration of the dummy during that time (in g's, with 1g = 9.81m/s2). In a different vehicle, the distance the dummy moves while being stopped is reduced from 0.720 m to 0.270 meter. Compute the average force on the dummy as that vehicle stops.
