The person has more kinetic energy before they jump than after they jump.
The person has less potential energy at the top of the platform than in the air.
The person's potential energy at the instant they jump is approximately equal to their kinetic energy the instant they land.
The person's kinetic energy at the instant they jump is approximately double their potential energy the instant they land.
Double the velocity of the object
Double the mass of the object
Double the potential energy
Double the temperature of the object
The square root of 2gh
One-half the mass squared
Two times ghm squared

Potential Energy can never be greater than Kinetic Energy
The energy in a closed system is always constant
The Kinetic Energy of a dropped object at the instant it hits the ground is roughly equal to the potential energy of the object at the instant it was dropped
It is not necessary to use Kinematics to discover the velocity of an object accelerated by gravity if you know it's initial Potential Energy and its mass.
Mass times velocity
Force times distance
Speed times acceleration
Time and space
The sum of their momentums after the collision is equal to the sum of their momentums before the collision
The momentum before the collision is always greater than the total momentum after the collision
The object with greater mass always has greater momentum
They both lose momentum at the moment of impact
