Question

A mountain climber jumps a crevasse of width W by leapinghorizontally with speed Vo. a) If the height difference between the two sides of thecrevasse is h, what is the minimum value of Vo for the climber toland safely on the other side? USE ONLY THE VARIABLES W, h, and appropriate constants. b) In this case, what is the climbers direction ofmotion on landing relative to the horizontal? EXPRESS ANSWER IN TERMS OF VARIABLES W, h, and appropriateconstants. a) If the height difference between the two sides of thecrevasse is h, what is the minimum value of Vo for the climber toland safely on the other side?

Explanation / Answer

A) If you know W and you know that he is jumping horizontally,you know that voy = 0m/s. h = voyt + 1/2gt2 t = (2h/g) vo = W/t vo = W/((2h/g)) B) vy = voy + gt vy = gt = g(2h/g) (vo2) + (vy2) =(vf)2 Take the square root of the sum of these two formulas:(W/((2h/g))2 + (g(2h/g)) Hope that helps Take the square root of the sum of these two formulas:(W/((2h/g))2 + (g(2h/g)) Hope that helps
