What is the Elastic Potential Energy Stored in a Compressed Spring?

AI Thread Summary
To find the elastic potential energy stored in a compressed spring, the formula Ep = 1/2 kx² is used, where k is the spring constant and x is the compression distance. In this case, a force of 5.00 N compresses the spring by 5.00 cm (0.05 m), allowing the calculation of the spring constant k as 100 N/m. Substituting k and x into the energy formula yields an elastic potential energy of 0.125 J. Understanding the relationship between force, spring constant, and compression is crucial for solving similar problems. The calculated energy reflects the work done in compressing the spring.

Homework Statement



A force of 5.00 N compresses a spring 5.00 cm. What is the elastic potential energy stored in the compressed spring?

Homework Equations



Ep=1/2kx2

The Attempt at a Solution



Epelastic needs to calculated. I really do not know how to get there. K=f/x
k=5N/ 0.05m
100 N/m
the answer is actually 0.125 J

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
