1. The problem statement, all variables and given/known data Exactly 2.9 seconds after a projectile is fired it has the velocity (9.0i +4.5j) m/s. What is the horizontal range of the projectile. 2. Relevant equations 3. The attempt at a solution Range = [((9.0i^2 + 4.5j^2)^1/2)^2 x sin2(arctan(4.5/9))]/ 9.8 m/s/s Range = 8.3 m but this is incorrect.
