1. The problem statement, all variables and given/known data(adsbygoogle = window.adsbygoogle || []).push({});

A ski jumper leaves the end of the slope, make a 35º with the horizontal and the slope making -45º with the horizontal. it has initial velocity of 8m/s. For him not to fall the tangent of the trajectory and the slope at the moment of impact should not be bigger then 20º, please verify if thats the case

2. Relevant equations

x = 8*cos(35)t

y = 8*sen(35)t -(1/2)gt^2

I have this exercise solved, what i'm trying to understand is why we want that y = -x, everything in pink is not in the original "drawing" of the problem

new here so hello everyone ^^
