To determine the effect of mass on kinetic energy, the student should drop two balls with different masses from the same height. This ensures that the only variable changing is the mass of the balls, allowing for a clear observation of how mass affects the kinetic energy when they reach the water.
So, the correct response is:
She should drop two balls with different masses from the same height.
