Question

Because of your knowledge of physics, you have been hired as a consultant for a new James Bond movie,"Oldfinger". In one scene, Bond jumps horizontally off the top of a cliff to escape a villain. To make the stunt more dramatic, the cliff has a horizontal ledge a distance h beneath the top of the cliff which extends a distance L from the vertical face of the cliff. The stunt coordinator wants you to determine the minimum horizontal speed, in terms of L and h, with which Bond must jump so that he misses the ledge.

Explanation / Answer

" the cliff has a horizontal ledge a distance h beneath the top of the cliff which extends a distance L from the vertical face of the cliff."

Time to fall: t = (2h / g)

Necessary horizontal speed: V = L / t = L*(g / 2h)

If you're using metric, then V = L*(9.8m/s² / 2h)

and English, then V = L*(32ft/s² / 2h)
