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? 312.5
What's the max height? 156.25
Here is what I got m(a) = 2*-(1/625)a + 1 = 0 which = -(1/312)a +...
This is probably easy for everyone on this forum but me. Can someone please explain this to me.
I need to simplify this:
(sqrt(x) - 4) / (x - 16))
am I on the right track by doing it this way...
(sqrt(x) - 4) / (sqrt(x) - 4) (sqrt(x) + 4) ...then cancel the (sqrt(x) - 4) in the...
