1. The problem statement, all variables and given/known data A gun fires a shell with a speed of 315m/s. Neglecting the effects of air resistance, calculate the maximum range of this gun 2. Relevant equations t=(vf-vi)/a v=d/t 3. The attempt at a solution it doesn't give me an angle so I am kind of confused on how to solve this problem. I know that to solve this question, i need to figure out the angle the shell is fired at, then use the given velocity to find the x and y component velocities, find time using velocity and acceleration (the first equation), and then use that time to find the range of the gun by solving for d in the second equation. I don't think i have enough information?
