How Do You Calculate the Potential Energy of a Spring?

AI Thread Summary
To calculate the potential energy of a spring, use the formula Ep = kx²/2, where k is the spring constant and x is the displacement from the equilibrium position. In this case, with a spring constant of 6.8 N/m and a displacement of 0.25 m, the potential energy can be determined. Additionally, consider the gravitational potential energy gained by the mass when stretched, which may vary depending on the spring's orientation. The discussion emphasizes the importance of showing initial problem-solving efforts before seeking help. Understanding both gravitational and spring potential energy is crucial for accurate calculations.

You've got both equations right, now you just need to figure a couple o' things out:
How much gravitational energy did it gain from being streched? (Because streching it could mean the center of mass is closer to or further from the Earth's center)
How much "spring"-energy did it gain?

It also depends on wether the spring lies on the floor, flat, or hangs from the cieling, eg.

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}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

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.
