Answer:
The kinetic energy when the film vault landed is 12744000J.
Explanation:
The kinetic energy is defined as:
(1)
Where m is the mass and v is the velocity.
By means of equation 1, the kinetic energy of the film vault when it landed can be determined
But 

Hence, the kinetic energy when the film vault landed is 12744000J.
