1. The problem statement, all variables and given/known data A cannon with a muzzle speed of 1,000m is used to start an avalanche on a mountain. The target is 2,000m from the cannon horizontally and 800m above the cannon. At what angle, above the horizontal, should the cannon be fired? 2. Relevant equations s^2 + b^2 = c^2 ? sinX = opposite/hypot. 3. The attempt at a solution Is this problem as simple as simple finding the hypotenuse and taking the sin to determine the angle? I do realize gravity acts on the ball but how do i incorporate gravity into an equation to find the velocity?
