Question

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 .

Answer 1

I just took the test for plato, the answers are 1250 and speed has a greater effect than mass

Answer 2

Speed has a greater effect than mass
