This is a fool's errand

There's no way to 'calculate' anything meaningful related to this. There are too many unknown factors and for what we know for sure (the range of the estimate), each has an error factor of at least two orders of magnitude.

Some examples: What was the source of the force? It could have been anything from steam to super nano thermite. Consider the speed at which the pressure built up and how that relates to the propulsion force on the lid once it was free.

What was the ultimate failure method of the container? Did the sides give first and offer the lock less resistance? Was one locking tab compromised by being dropped at some point? (even a well placed scratch could affect this.) Did one side let go before the other? So many questions.

What other projectiles 'helped' the lid to find it's ultimate path? With a very high velocity pressure build up (such as dynamite or C4), those projectiles would impact the lid, compromise it in some unpredictable way, and add to its acceleration.

How high did the lid go before stopping and returning to earth? Anything sending it higher than about 10' higher than the building is conceivable. Sure that may impart great sideways component to the landing compared to the vertical drop, but have you ever seen a football land at an oblique angle and bounce back in the reverse direction?

I don't really see the point in even pursuing this unless many other details are provided first.
