Find at what angle should the cannon be fired

Reference no: EM13708554

Question: A cannon with a muzzle speed of 990 m/s is used to start an avalanche on a mountain slope. The target is 2000 m from the cannon horizontally and 810 m above the cannon.

Part A: At what angle, above the horizontal, should the cannon be fired? (Ignore air resistance.)

I need help to determine at what angle, above the horizontal, should the cannon be fired.
