1. The problem statement, all variables and given/known data In the game of darts, the player stands with feet behind a line 2.36 m from a dartboard, with the bull's-eye at eye level. Suppose you lean across the line, release a dart at eye level 2.23 m from the board, and hit the bull's-eye. Find the initial velocity of the dart, if the maximum height of its trajectory is 1.45 cm above eye level 2. Relevant equations y=v_0t+.5gt^2 x=v_0t v_f=v_i+at v_f^2=v_i^2+2ax 3. The attempt at a solution I tried to find the angle at which the projectile was thrown by using inverse tangent of .0145/1.115 but that did not give me the correct angle. I tried plugging in these numbers and manipulating the equations but I could not get anything to work out.
