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 is

joules. Susan’s kinetic energy is greater than Hannah’s because

Answer:

Susan’s Kinetic Energy Is greater because her Velocity’s greater when compared with Hannah’s.

The difference in their Mass isn’t so great so the chief difference lies with their Velocities.

Recall

KE=½MV²

KE depends on the Mass and square of the velocity of the person/object.

You can evaluate the Kinetic Energies of Susan and Hannah to still prove this using the formula KE=½MV².
