## Homework Equations

y = (x-h)^2 + k

## The Attempt at a Solution

y = (x-95)^2 + 10 ??? We were assigned this in class but my teacher never taught us anything about these kinds of problems. I've learned basic parabolas and equations in class but I don't know how to apply it to this assignment because the cannonball lands in the net at a different height from the original platform. I also have no idea how to find the angle of the cannon. Can someone help me out? Thanks!
