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
s = ut+0.5at^2
h = 0 + 0.5*9.8*t^2
=> t = 0.451753951*sqrt(h)
d = ut
=> L = u*0.451753951*sqrt(h)
=> u = L/0.451753951*sqrt(h) = 2.213594362*L/sqrt(h)
