An ideal spring has a spring constant (force constant) of 2500 n/m, is stretched 4.0 cm, how much elastic potential energy does it possess? (a) 3j (b) 0.00j (c) 1j (d) 2j (e) 4j

Elastic potential energy, E = 2 J

Explanation:

It is given that,

Spring constant of the spring, k = 2500 N/m

The spring is stretched to a distance of 4 cm i.e. x = 0.04 m

We have to find the elastic potential energy possessed by the spring. A spring possessed elastic potential energy and it is given by:

E = 2 Joules.

Hence, the correct option is (d) " 2 Joules ".
