# I'm back problem - 3 (Is this just mechanics?)

Calculus Level 5

A ball is thrown from the edge of a cliff $$50\: m$$ high, at an angle of $$30^\circ$$ upward from the horizontal and at a speed of $$10\text{ m/s}$$. Refer to (2) in the figure. Neglecting air friction and other external factors, determine the length $$A$$ of the path traveled by the ball (depicted in blue dashed lines). Express your answer as $$\lfloor A \rfloor$$.
