this equation is a standard form for when
an object is released from an initial height of 320, decreasing in height due to gravity on earth at sea level.
It reaches sea level or ground level
when -16t^2 =-320
t^2 = 20
t= sqr20 = about 4.5 seconds
it reaches max height when
-32t =0 or t=0, max height = 320
