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( 1080 , 1250 ,1350,or 1500) is joules. susan’s kinetic energy is greater than hannah’s because ( the speed is a greater effect than mass, mass has a greater than speed , mass and speed have same effect or mass & speed does'nt have any effect .
