Susan and Hannah are each riding a swing. Susan has a mass of 25 kilograms, and Hannah has a mass of 30 kilograms. Susan's swing moves with a velocity of 10 meters/second, while Hannah's swing moves with a velocity of 8.5 meters/second. Susan's kinetic energy is (1080,1250,1350, or 1500) joules. Susan's kinetic energy is greater than Hannah's because: Speed has a greater effect than mass, Mass has a greater effect than speed, Mass and Speed have the same effect, or Mass and Speed dont have any effect?
