A projectile is fired from the ground with initial velocity of 960 ft/sec, at an angle of 30� above the horizontal. If the height as a function of time t is given by h(t)=480t�16t^2, find its maximum height.
----------------
h(t)=480t�16t^2
Max height is the vertex of the parabola at t = -b/2a
t = -480/-32 = 15 seconds
--> h(15)
