Hi guys, Please, someone can help me to solve some simple equations?

I Need to shoot a projectile with 20 grams at 15 meters and 15°.

So, I'm triyng to calculate the velocity and Force and what I will need to make this succesfull.

My Calcs:

*************************************************************************

Velocity= √(R*g)/sen θ

V= √(15m * 9,81) /sen15

V= 46,86 m/s

***

I= ΔQ or

I= (0,020kg * 46,86 m/s) - (0,020kg * 0 m/s)

I= 0,937 N.s

***

(I = Impulse // I= Force * Time)

0,937 N.s = Force * 0.1s

Force = 0,937 / 0,1 = 9,37 N.

**************************************************************************

This means I need to put just 9,37 Newtons on 0,1 seconds to shoot a 20 grams projectile at 15 meters and 46,86m/s? (at 15°)

Thank you for your attention and sorry for my bad english.

*Qend - Qinitial*. (Q = moviment quantity. Q= m.V)I= (0,020kg * 46,86 m/s) - (0,020kg * 0 m/s)
