Homework Help Overview

The discussion revolves around calculating the launch speed of a projectile based on the distance it travels and the angle of launch. Participants are exploring the relevant equations and concepts related to projectile motion.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants inquire about the projectile equations and express uncertainty about deriving the launch speed from known variables. There are mentions of specific equations and attempts to manipulate them to find the desired speed.

Discussion Status

The discussion is active, with participants sharing equations and referencing external resources. Some guidance has been offered regarding the use of projectile formulas, but there is no explicit consensus on the approach to take.

Contextual Notes

Participants are mindful of forum rules regarding the provision of direct answers and are navigating the constraints of the discussion format while seeking clarity on the topic.

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 [tex]v_0[/tex].EDIT: Don't delete the thread( can you even do that?), were you able to get [tex]v_0[/tex]? That is your goal, so what did you get for [tex]v_0[/tex]?

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

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