Sagot :

Answer:

0

Explanation:

Potential energy of the body is converted to kinectic enery as it falls thus the formula massx gravity x height at the instant it hits the ground the height is 0 putting this into the equation the potential energy is 0 since the potential energy is converted to kinectic energy potential energy is equal to kinectic energy then the kinectic energy at the instant it hits the ground is 0
