Problema Solution
A projectile follows a parabolic path whose height, in meters, is given by the function f(x) = -x^2+2x+2. Find the maximum horizontal distance that the projectile may cover.
Answer provided by our tutors
The horizontal distance, x, is greatest at f(x) = 0 and x>0
-x^2+2x+2 = 0
by solving we find:
x = 2.73 m
