[SOLVED] Projectile Motion 1. The problem statement, all variables and given/known data You are shooting a cannon from a height of 11.23m off the ground. The target is 20.36m away. The angle of projection is 30 degrees. What does the initial speed need to be in order to hit the target? 2. Relevant equations When I look at this problem I just cannot solve it. I personally don't think I have enough information but it has really been bugging me. 3. The attempt at a solution I know I need to figure out one of the velocities, either for the x or the y axes in order to solve for the initial velocity. The only information I have is: [tex]\Delta[/tex]y=11.23 a=-10 [tex]\Delta[/tex]x=20.36 a=0 I tried using the range formula before remembering that it can only be used when the initial and final velocities are the same.
