A bullet of mass `10 gm` is fired horizontally with a velocity `1000 ms^(-1)` from a riffle situated at a height `50 m` above the ground. If the bullet reached the ground with a velocity `500 ms^(-1)`, the work done against air resistance in the trajectory of the bullet is (in joule) `(g = 10 ms^(-2))`.
