1. The problem statement, all variables and given/known data Basically, there is a projectile shot from a cannon. When shot, the projectile passes over a net, just barely, which is placed 6.0m away from the cannon, horizontally. The cannon is angled at 40 degrees above the x-axis. The problem is asking for the muzzle speed of the cannon and how high the net is. 2. Relevant equations delta x = .5(Vf + Vi)t Vf=at + Vi delta x = .5at^2 + Vit Vicos40 = X component Vi Visin40 = Y component Vi 3. The attempt at a solution I know that delta x would be the 6.0m, X component acceleration is 0, and Y component acceleration is -9.8m/s^2. The problem i am running into is working with the limited number of givens here. I know i need to solve for the time it takes to travel to the net(6.0m horizontally). I'm sure it will involve several equations and substitutions to solve for algebraically(we are using non-calc methods in the course), but I'm not sure where to go with this problem.
