Question 110964
plugging in 1 for t will give the height after 1 sec.


this is the equation of a parabola ___ the maximum (or minimum) lies on the axis of symmetry


the general equation for the axis of symmetry is x=-b/2a
___ in this case, t=-v0/(2(-16)) ___ this is the time to maximum height
___ plugging this t into the equation will give the maximim height
