Homework Statement
200g weight
spring unstretched length: 0.238m
spring stretched( 200g hanging on spring): 0.305m
Problem: Need to find length of a cord long enough so that the 200g weight can have the best bungee jump ever (barely not touching the floor which is 10m high)
Homework Equations
K=mg/x
The Attempt at a Solution
I calculated the constant of the spring in Newtons per meter : 29N/m
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXX
I don't get the constant, because the constant is just the length of the spring with the weight on it, and the spring stretches more then just 0.305m, speacialy if i drop it from 10m up.
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXX
Please help me.
**Conclusion**
29N/m is (to me) a useless value and have no idea on how to get the length of string so that my "jumper" does not die.
Notes: i tried to make this as clear as possible.
Why i need help: Because i would like to know how bungee jumping works. (presentation in english class, need to understand all of it and not just read stuff on google.)
it is a demonstration so please help me i don't want to look like a fool infront of my class when my "jumper" hits the floor.
