Alex hits the softball with the initial velocity of 64ft/sec. and the initial height of 4ft.
h(t)= -16t2 + vi t + hi
h(t) = the height of the object after t seconds
t = time in seconds
vi = initial velocity
hi = initial height in feet
i) put equation in vertex form by completing the square.
ii) Write vertex; what x-value of vertex means/what y-value of vertex means?
iii) After she hits ball, when will ball hit the ground?
iv) how much time will it take if outfield will catch it five feet above ground?
