If you pay attention, step 5 is the exact equation I derived.
let me ask you this, why do you feel it is necessary to find the max height. It is irrelevant to this problem.?
P(t) = -4.9t^2 + 11.5cos(49.5)t + 1.6
It is a graph of the path of the flight, as you will see the object velocity changes from positive to negative..only the zero of this equation is when the ball falls 1.6 m further than the designated initial position of zero(ie y=-1.6)
Im looking at the exact form of this problem in a physics text right now
