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?
