Answer:

Kinetic Energy of magnitude \frac{1}{2\\}mgx and potential energy of the same magnitude.

Explanation:

Initially , the body is at rest with no velocity , therefore initial KE = 0

Initial PE = mgx , as it is a height of x from the earth's surface

When it falls it loses the potential and has PE =  \frac{1}{2\\}mgx

Since energy has to be conserved ( We can't create or destroy energy)

Loss in PE = Gain in KE

Therefore KE = mgx - \frac{1}{2\\}mgx  =  \frac{1}{2\\}mgx
