    Cannonbal Question

    Hello, I am having a hard time with this one, can anybody help? Cannonball fired on 45 deg angle from horizontal. Initial position is origin. initial velocity 100sqrt(2) ft/sec. Trajectory is y=x-(x/25)^2 where y>=0. How far till it hits the ground? What's the max height? Thanks
