- At a carnival game, two balls are Identical in mass and radius, but one is made of steel and one is made of rubber. The game is to throw them at a bowling pin and try to knock it over. If the balls are thrown with the same speed and hit the same spot on the bowling pin, which Is more likely to knock it over? A. The steel ball B. Without knowing more information, this cannot be answered. C. Both are equally likely since they have the same momentum D.
