A car is stationary at a stop sign when it is hit directly from behind by a truck of mass 3000 kg which was travelling at a speed of 9 ms" immediately before the collision. The two vehicles lock together and move forward with an initial speed of 6 ms. Question 105 (1994 Question 6) What is the mass of the car? Both drivers were wearing correctly adjusted seatbelts at the time of the accident, and the vehicles had strong supporting seat backs with head restraints. Question 106 (1994 Question 7) Which statement (A - D) below best describes the forces arising from the impact, which act on the drivers? A. Each driver felt an increased force due to the seatbelts. B. The driver of the car felt an increased force due to the seatbelt, but the driver of the truck felt an increased force due to the back of the seat. с. Each driver felt an increased force due to the back of the seat. D. The driver of the truck felt an increased force due to the seatbelt, but the driver of the car felt an increased force due to the back of the seat. Each driver had a mass of 72.0 kg. During the collision, the driver of the car experienced an average force of 8000 N. Question 107 (1994 Question 8) How long did the collision take? Question 108 (1994 Question 9) What was the magnitude of the force experienced by the driver of the truck?
