Question
Chapter 4: #88: James S Walker, 4th edA mountain climber jumps a crevasse by leaping horizontal withspeed Vo. If the climbers direction of motion of landing is belowthe horizontal, what is the height difference h between the twosides of the crevasse.
I'm completely stuck on this question. I look at theanswer:
I algebraically understand everything up to the part wherethey say:
vsin/vcos = gt/vo
I don't understand how you get to this point.
But on another note, I was wondering how to tackle thisproblem.
Thanks,

Explanation / Answer
Ans. if the velocity be v making an angle with horizontal, then horizontal component velocity=vcos & vertical component velocity=vsin Now givenvcos=v0 from v=u+ft 0=vsin-gt vsin=gt (vsin)/(vcos)=gt/v0 [proved] for the givenproblem, from the above relation u can get t & then putting this t inthe following relation u can get h value. s=ut+0.5ft2 h=vsin*t-0.5*g*t2 alternatively, u can use thefollowing relation, v2=u2+2fs 02=(vsin)^2-2*g*h h=(vsin)^2/(2*g) alternatively, u can use thefollowing relation, v2=u2+2fs 02=(vsin)^2-2*g*h h=(vsin)^2/(2*g)Related Questions
