- The following are multiple choice questions. No explanations required.Choose the correct answer g) Two balls are dropped from the same height. Both balls bounce (perfectly elastic) when they hit theground. Ball A has half the mass of ball B. Which ball has a greater speed after the bounce?h) Two balls are thrown from the same initial height above the ground. Ball A is thrown straight down.Ball B is thrown straight up. Both balls have the same initial speed. Which ball has the larger speedwhen it hits the ground?i) Two identical balls roll down a frictionless track. The tracks are the same height from top to bottom.Track A is straight and track B is curved. If both balls are released from rest, which ball reaches thebottom with the larger speed?j) You see two identical freight trucks driving down the highway.
