A 500-kg car traveling east at 30.0 m/s collides with an 800-kg truck traveling north at 20.0 m/s at an intersection. The vehicles stuck together after the collision. The coefficient of sliding friction between both vehicles and the road is two 0.300. Assume that the collision takes place on a level road. 1. Which of the following statements is FALSE? The kinetic energy of the system is not conserved during the collision. The friction between the vehicles and the road affects the motion of the vehicles after collision. The momentum of the car after the collision is equal to the vector sum of the momentum of the car before the collision and impulse exerted by the truck to the car during the collision. The final speed of the combined mass after the collision is equal to the sum of the initial speeds of the car and the truck.
