Homework Statement
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?
Homework Equations
s^2 + b^2 = c^2 ?
sinX = opposite/hypot.
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?
