    Launch Speed
AI Thread Summary
To calculate the launch speed of an object using the distance traveled and the angle of launch, the projectile motion equations are essential. The range formula for projectile motion can be expressed as R = (v^2 * sin(2θ)) / g, where R is the range, v is the launch speed, θ is the launch angle, and g is the acceleration due to gravity. Participants discussed manipulating this formula to isolate the launch speed (v_0) based on known distance and angle. The conversation highlighted the importance of understanding the underlying equations and encouraged experimentation with them to derive the desired values. Overall, the focus was on applying these principles to effectively calculate launch speed.

How do you calculate the launch speed of an object using only the distance it travels the angle of launch?
If there is an equation, I would be very happy if you could tell me what it is.
This is the only thing I need.
 
Physics news on Phys.org
do you know the projectile equations?
 
Yes, I do, I know it has to do with sin^2(theta)=2sin(theta)*sin(theta)
I just can't get this equation which would help get the average launch speed.
 
what is the projectile formula for range?

(i can't tell you the answer, as per rules of the forum)
 
v^2-v^2=2a delta x

I know that this is purely based on volunteer work and help, but I would appreciate it if you don't draw this out. If you can get to the point, please do.
 
or delta x=vt-(1/2)at^2
 
haha, ****, why didn't i think of wikipedia.
Thanks man!
 
No sarcasm there.

Do I delete this thread?

Darn The legend beat me to it. But yeah basically just play around with that formula to get v_0.EDIT: Don't delete the thread( can you even do that?), were you able to get v_0? That is your goal, so what did you get for v_0?

just easy stuff, playin around with equations..
You are welcome, hailfire..

@MysticDude: yup, beat you to it! :biggrin: hehe
