I'll post these in two messages to make this easier. First problem:
I'm pretty stuck on this one. I've tried juggling all the kinematics equations but the best I can do is solve x=v*cos(theta)*t for t and drop it into y=(1/2)gt^2 + v*sin(theta)*t. This yields the standard Range equation, but I can't solve that for theta. I'm just not sure how to derive the right equation.A cannon with a muzzle speed of 1000 m/s is fired at a target 2000m away horizontally and 800m above the cannon vertically. Find the necessary angle to hit the target.
