a ski jumper leaves the ski track moving in the horizontal direction with a speed of 25.0 m/s. The landing incline below him falls off with a slope of 35.0 degrees. where does he land on the incline? I already know how to use formulas to plug and chug to get an answer. I need to know why the answer is the only answer. what is the physical reasoning behind it because geometrically, the vector can be as long as it wants to be without changing that angle. What is the reasoning behind what the maximum magnitude the vector can have? how am i suppose to know this? is maximum magnitude the magnitude that is only before exceeding the magnitude that will force the skier into certain death? is it the snow that determines the limit? the ramp? what is it? i dont see it at all! we only get one angle so the triangle can be as big as it wants to be!
