1. The problem statement, all variables and given/known data Please see attached. 2. Relevant equations v = u + at s = ut + ½ at² v² = u² + 2as 3. The attempt at a solution I've managed to get the first part of the question applying Bernoulli's principle and then the equations of motion above by considering separately the vertical and horizontal. As for the second part, I'm not sure how to go about it. I believe that I would simply need to plug what's known into a certain formula and then solve for h; I expect that would yield a quadratic equation with two solutions for h. But I'm not sure what I need to be using to get this?
