A car and a truck are both travelling at the speed limit of 60kilometers per hour but in opposite directions. The truck hastwice the mass of the car. The vehicles collidehead-on and become entangled together. Required:
a. During the collision, how does the force exerted by thecar on the truck compare with the force exerted by the truck on thecar? Explain.
b. In what direction will the entangled vehicles move aftercollision, or will they be stationary? Support your answer, referring to a physics principle.
c. Determine hte speed (in kilometers per hour) of thecombined wreck immdeiately after the collision.
d. How does the acceleration of the car compare with theacceleration of the truck during the collision? Explain.
e. Both the car and truck drivers are wearing seat belts. Which driver is likely to be more severly jolted in the collision?Explain.
f. The total kinetic energy of the system decreases as aresult of the collision. Is the principle of conservation of energyviolated?
