    Length Spring
AI Thread Summary
The discussion revolves around calculating the length of a spring with two identical weights hanging from it, using the spring constant k and the relaxed length L0. The equation 2t = -kx is introduced, but the variable "t" is questioned due to a lack of clarity in the provided figure. Participants request a visual representation or a more detailed description of the setup to better understand the problem. The absence of a clear diagram hinders progress in solving the problem. Accurate visualization is essential for resolving the physics involved in this scenario.

Homework Statement



Two identical weights of mass m hang motionless
from massless strings attached to the two ends of a
spring, as shown in the figure. The spring constant
of the spring is k. What is the length of the spring,
if its relaxed length is L0?

Homework Equations


f = -kx
f = ma


The Attempt at a Solution



2t = -kx

Could you please either scan and attach the figure, or at least describe it?

The Attempt at a Solution



2t = -kx

Where did the "t" come from?
 


No picture - can't tell what is going on from the written description.
 


OK, so where does t come from?
 


The picture sort of looks like this ;

______springIsHereOntheTable_______
|...ignore these dots......|
|.........|
|.........|<-those lines at the end are a string.
m1.........m2

so the spring is on a table and attached to the left if it is a string which passes a
massless pug at the corner of the table and m1 is hanging on that string at the left
side of the table and m2 is attached to the string on the right side which is also hanging
on the string.
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
