Answer:
hello your question is incomplete attached below is the complete question
answer : 54 m
Step-by-step explanation:
Applying jet equation of Parabola
(x-h)^2 = 4p (y-k) where (h,k) = 0
x^2 = 4py and this passes through ( 48, 24 )
(48)^2 = 4(p)(24)
hence P = 24
x^2 = 96h at x = 72 and y(h) unknown
= 72^2 = 96(h)
h = 72^2 / 96 = 54 m
