Use KE=/frac{1}{2}mv^{2}

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 ( * 1,080, 1,250, 1,350, 1,500) 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 don't have any effect).
