an easy physics question?
A force of 9.1 N holds an ideal spring with a 30.1 N/m spring constant in compression. How much potential energy is stored in the spring?
i thought it pretty straight forward, but its not...
its not mgd or 0.5kx^2
i dont no what else it could be so..
Update:man, the grading system eats my points..never mind to this problem..move on...omg...i cant believe it eats my points like that

Verified answer
x = F/k = 9.1/30.1 = .302 m
E = ½kx² = ½*30.1*.302² = 1.376 J
This IS the correct answer, regardless of what the computer says.
There MUST be some way you can challenge this. Good luck.
Physics isn't an uncomplicated difficulty, yet then if it have been uncomplicated then being good at it does not be so awesome. some actual everyone seems to be good at math, some at technological awareness, some are proficient with languages, and others are artistically proficient. Too many actual everyone seems to be boastful sufficient to think of that through fact they are truly good at some issues that they could be waiting to do something they placed their concepts to. it particularly is actual no longer actual. locate what you like and concentration on that. and do purely the terrific you may with the matters which you do unlike or comprehend.
you just need to find the potential energy formula for a spring ..
