She should drop two balls of the same mass from different heights.
She should drop two balls of the same mass from different heights.

She should drop two balls with different masses from different heights.
She should drop two balls with different masses from different heights.

She should drop two balls with different masses from the same height.
She should drop two balls with different masses from the same height.

To determine the effect of mass on kinetic energy, the student should investigate by varying the mass while keeping other factors constant. Therefore, the best option would be:

She should drop two balls with different masses from the same height.

This method allows her to observe how the differing masses affect the kinetic energy of the balls without the influence of different heights.
