A cannon ball launcher is situated 10.0m from the base of a 30.0m high cliff. The launcher is aimed towards the cliff at an angle of 77 degrees above the horizon. A cannonball is shot so that it just barely clears the edge of the cliff. With the given information figure out the following: a) How much time does it take for the cannon ball to reach the edge of the cliff? b) What's the initial speed of the cannonball? c) Where on the cliff top does the cannon ball land? (how far from the edge?) X 30m V₁ 77°
