20joules, bcoz it loses gravitational potential energy of 20joules, in the absence of gpc, kinetic energy will be acquired

Answer:The kinetic energy is 20 j.
Explanation:
Given that,
Gravitational potential energy = 20 j
Potential energy : It is the energy which is possessed by body due to virtue of its position.
Kinetic energy: It is the energy which is possessed due to the motion of object.
According to the law of conservation of energy,
Potential energy + Kinetic energy = constant
At the top the kinetic energy would be zero.
At the bottom the potential energy will be converted completely in to the kinetic energy.
Hence, The kinetic energy is 20 j.
