I need help with calculating the initial velocity of a spring used an a bean catapult.

Question

mathmale · Answer

You'd be more likely to get helpful responses if you'd illustrate or describe the problem you're working on (instead of merely stating that you need help).

Is it possible to find the initial velocity of a spring by using trigonometry?

anonymous · Answer

and hooke's law?

anonymous · Answer

My group created a bean catapult and we have to make a mathematical model for it. We used a spring.

Again, mangoes, I need to see an illustration (or to read a verbal description of the problem) BEFORE I can give you any meaningful feedback.  Since the Draw utility is not functioning, could you photograph the problem statement and post the image here?

So much better, having a photo!!  I'm waiting for your "calculations.pdf" to load.

mathmale · Answer

Your calculations.pdf doc does not load at my end.

Regarding the spring constant:

F=kx, Hooke's Law.  You need some way of measuring the force, F, that results in the spring's stretching from 2 inches to 3.11 inches (x=3.11-2.00=1.11 inches).  

How did you find the spring constant of that "spring similar to the one we used"?

Thanks for sharing this pdf doc; this time I was able to open and view it.  
With what, specifically, would you like help?  I'd be glad to focus on specific questions, but am not up to reviewing the entire document and giving you feedback on the whole thing.
