1. The problem statement, all variables and given/known data a mountain climber plans to jump from A to B over a crevasse. Determine the smallest value of the climbers initial velocity Vo and the corresponding value of the angle alpha so he lands at B 2. Relevant equations A to B is 1.8m horizontal distance and B is lower than A by 1.4m Xx=Vo*T Xy=Vo*T-.5*9.81*t^2 3. The attempt at a solution Distance X = 1.8 = cos(alpha)*Vo*t => T=1.8/(cos(alpha)*Vo) Distance Y = -1.4= Vo* (1.8/(cos(alpha)*Vo)-.5*9.81*(1.8/(cos(alpha)*Vo))^2 My question is I don't know what other equation to use since I have two unknown equations I thought I could use the Range equation R= (Vo^2/g)*Sin(2alpha) but this is not on level ground so I dont think it will work. Ideas?
