how did the mass and speed of a person affect them out of kinetic energy they have after jumping on the diving platform

more mass and more speed means less kinetic energy
less mass and more speed means more kinetic energy
more mass and more speed means more kinetic energy
more mass and less Speed means more kinetic energy

Actually, the correct relationship between mass, speed, and kinetic energy is:

More mass and more speed means more kinetic energy.
Less mass and more speed means less kinetic energy.
More mass and less speed means less kinetic energy.

Kinetic energy is directly proportional to both mass and speed. When both mass and speed increase, the kinetic energy of a person will increase. Conversely, when either mass or speed decreases, the kinetic energy will also decrease.
