In the tragic case that a semi-truck collides with a small, two-door sports car, which of the following statements most accurately characterizes the forces involved. a. The truck exerts a smaller force on the sports car than the sports car does on the truck. b. The force the truck exerts on the sports car is the same as the force the sports car exerts on the truck. c. The truck exerts a larger force on the sports car than the sports car does on the truck. Which of the following is the best example of an Elastic Collision? a A collision between two automobiles. A collision between two billiard balls. b. c. A basketball bouncing off the floor. (:1. An egg colliding with a brick wall. Which of the following is/are true? (select all that apply) a In all collisions, momentum is conserved. In all collisions, kinetic energy is conserved. b. c. Perfectly elastic collisions do not occur in the real world. (:1. In this week's lab, we will need two smart carts of the same color. In an inelastic collision, kinetic energy is not conserved. Where does it go? (select all that apply) a. It is transformed into heat. b. It is transformed into momentum such that momentum is conserved. c. It is transformed into gravitational potential energy. (1. It is used to deform the colliding obj ects. If I were to drop an egg off a cliff, it begins to accelerate toward the ground, until it hits the ground and splattered. Is momentum conserved in this situation? a. Yes. The speed of the egg is zero both before and after the fall, so momentum did not change. b. No. Momentum is never conserved. c. Yes. The earth is also pulled toward the egg, keeping the momentum constant during the whole fall. (:1. No. The speed of the egg changes throughout the situation, but there is nothing else in the scenario that also moves to keep momentum conserved
