- Homework Statement
- A 1500 kg rocket is launched with a velocity v0 = 115 m/s against a strong wind. The wind exerts a constant horizontal force Fwind = 1450 N on the rocket. What is the rockets maximum range?

- Relevant Equations
- R=(V0^2*sin(2a))/g

the first question was At what launch angle will the rocket achieve its maximum range?

and i found the right answer it was 42.186deg.

but now i don't understand what I am doing wrong i put v0,a,g in the equation of range and its wrong and i don't undertand why

here is what i try:

R=(115^2*sin(2*42.186))/9.81

and my answer is 1341.615m

and it was wrong so than i thought maybe i need to divide by 2 and it was still wrong i would like for some help with it because i don't know what else to do.
