An archer shoots an arrow horizontally at a target 17 away. The arrow is aimed directly at the center of the target, but it hits 51 lower. What was the initial speed of the arrow? so I know I need to find time and then solve for the distance so I entered in 17^2 + .51^2 and got 17.0076^2 and tried to solve for distance and time but that did not work....I really have no idea what im doing. How do you work these types of problems?
