The following are multiple choice questions. No explanations required. Choose the correct answer ( A / B / equal / can’t tell ). 1A) Two blocks are on a table. Block A has double the mass of block B. Is the center of mass of the system closer to block A or block B? 1B) Two blocks slide a distance d on a surface without friction, starting from rest. Both blocks have the same applied force F, acting parallel to the motion. Block A has twice the mass of block B. Which block has more Kinetic Energy when it has traveled the distance d? 1C) Two blocks slide a distance d on a surface without friction, starting from rest. Both blocks have the same applied force F, acting parallel to the motion. Block A has twice the mass of block B. In which case did the applied force F do the most work? 1D) The earth orbits around the sun. Which force has a larger magnitude? A – force of the sun on the earth B – force of the earth on the sun 1E) Two balls are dropped from the same height. Both balls bounce (perfectly elastic) when they hit the ground. Ball A has half the mass of ball B. Which ball has a greater change in momentum during the bounce? 1F) Two balls are dropped from the same height. Both balls bounce (perfectly elastic) when they hit the ground. Ball A has half the mass of ball B. Which ball has a greater speed after the bounce? 1G) 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 speed when it hits the ground? 1H) 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 the bottom with the larger speed? 1I) You see two identical freight trucks driving down the highway. In both cases, the trailer is bouncing up and down on its springs. Truck A is heavier than truck B. Which truck bounces with a higher frequency?
