Aset of crash tests consists of running a test car moving at a speed of 11.4 m/s (25.08 m/h) into a solid wall. strapped securely in an advanced seat belt system, a 55 kg (121 lbs) dummy is found to move a distance of 0.78 m from the moment the car touches the wall to the time the car is stopped. calculate the size of the average force which acts on the dummy during that time.
