Question

In the absence of air resistance, a projectile that lands at the elevation from which it was launched achieves maximum range when launched at a 45∘ angle. Suppose a projectile of mass m is launched with speed v0 into a headwind that exerts a constant, horizontal retarding force F⃗ wind =−Fwindi^.

By what percentage is the maximum range of a 0.900 kg ball reduced if Fwind = 0.600 N ?

Already got the wrong answer with the following values: 8.45%, 8.5%, 6.8%

Please Help tried a few different equations, none seem to work.
