Is a spring stores 5 j of energy when its conpresses by 0.5 m what is the spring constant of the spring?

k = 40 N/m

Explanation:

A spring's energy is given:

U is the energy in the spring, k is the spring constant and x is the spring displacement.

We are told that the spring stores 5J of energy, therefore, U = 5J. We are also told that the spring is compressed by 0.5m, so the spring x = 0.5m

k = 40 N/m

Hope this helps!

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
