<span> s = -16t^2 + 64t + 3
v = -32t + 64
the maximum height occurs when v = 0:
-32t + 64 = 0 when t = 2 sec
the maximum height is
s = -16(2^2) + 64(2) + 3 = 67 ft
the range is [ 3, 67] </span>
I think it’s A.I’m sorry not that sure
Sorry this is not a answer but I have to use this as one due to the question asking.... whelp
