Question

Question 17 (1 point) Two balls collide that were initially moving. After the collision, the balls are both still moving but in different directions. Momentum and kinetic energy were both conserved. What type of collision happened? A) Completely inelastic B) Elastic C) Depends if sound was created D) Inelastic Question 18 (1 point) To catch a water-filled balloon without breaking it, people allow their hands to move with the balloon upon catching it. This works because: A) the balloon's momentum changes more slowly B) there is less force applied C) there is less impulse D) only two above are correct E) A, B, & C are correct
