A51 A motor car collides with a crash barrier when travelling at 100 kmh-| and is brought to rest in 0.1 s. Ifthe mass of the car and its occupants is 900 kg calculate the average force on the car by a consideration of momentum. Because of the seat belt, the movement of the driver, whose mass is 80 kg, is restricted to 0.20 m, relative to the car. By a consideration of energy calculate the average force exerted by the belt on the driver.
