So now we want to do two calculations, firstly, the time it takes to jump a 50ft hole in the freeway, and secondly how far the bus will fall in this time.

If the bus is travelling above 50mph, (let’s give them the benefit of the doubt and assume it is going about 75mph (33ms^-1)).

To travel 50ft (15.24m which is 3.28ft to a metre), will take

15.24/33.5 = 0.454 seconds.

In that time the bus will have fallen - according to our formula s=0.5at²:

0.5 x 10 x 0.454² = 1.03m

So does the film hold up scientifically?
