Spring Constant (this is really easy, I'm just dumb haha)

AI Thread Summary
To determine the spring constant, the formula F = kx is used, where F is the force applied, k is the spring constant, and x is the extension of the spring. In this case, the initial length of the spring is 1.5 m, and it extends to 1.55 m under a load of 55 N, making the extension x equal to 0.05 m. The equation simplifies to 55 = 0.05k, allowing for the calculation of k. The confusion arose from previous experiments with springs that yielded smaller constants. The discussion confirms the correct approach to finding the spring constant.

A spring 150-cm long extends to a length of 155 cm when it supports a load of 55 N. Determine the spring constant.

F = kx

x1= 1.5 m
x2= 1.55 m
F = 55 N
k = ?

Now, "x" in F = kx is x2-x1, right? So the formula would be 55 = .05k?

Sorry, I know this is simple, I just am having a momentary lapse.

Perfectly correct. :smile:
 
Awesome. That's what I thought, but when I was experimenting with springs the constant was always a lot smaller so I got confused :P

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...
