1. The problem statement, all variables and given/known data A cannon has to fire a ball through a window in the wall. The window is 10 meters at the Y axis, and 8 meters (away from the cannon) at the X axis. The window is just slightly bigger than the ball (let's suppose that the dimensions are negligible). Find the required launching power. Ball's mass: 0.6 kilograms Angle of launch: 51.34 degrees 3. The attempt at a solution I seem to be getting a strange initial velocity, way too high. Is my formula off? Or calculations?
