As someone who has just started Physics, when triangles were introduced in my physics it caught me in surprise. If the legs of triangle were heights It would somewhat make more sense to me, but our teacher says their are velocities. I do not understand. For example : A pitched ball is hit by a batter at 49 degrees angle. It just clears the outfield fence, 94 m away. the acceleration of gravity is 9.8 m/s squared. Find the velocity of the ball when it left the bat. Assume the fence is the same height as the pitch.
