Find the work done by the spring force on a box

AI Thread Summary
The discussion focuses on calculating the work done by a spring force on a box using the equation Wspring = ∫-k*xdx, with integration limits from 0 to 12 cm. The calculated work is -1.24 Joules, derived from the spring constant of 172 N/m. There is a mention of confusion regarding the values used in the calculation, specifically mixing up 12 cm and 175. The participants acknowledge common mistakes in calculations, highlighting the challenges faced in physics problems. Overall, the thread emphasizes the importance of careful attention to detail in solving spring force problems.

Homework Equations

The Attempt at a Solution


Wspring = ∫-k*xdx
limits of integration are 12 and 0
So
[0 - .12^2/2]*172 = -1.24J of force
Getting 1.8/2 points for this anser

aw crap my dyslexicia is kicking in
 
Thank you
 
i think i mixed the 2 at the end of 12cm and the 175 together

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
