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 Qend - Qinitial. (Q = moviment quantity. Q= m.V)
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.
