5.) A spring with a spring constant of 500 n/m is stretched 1 meter in length. How much EPE does it have? *
500 Joules
250 Joules
1500 Joules

250J

Explanation:

Given parameters:

Spring constant  = 500N/m

Extension  = 1m

Unknown:

Elastic potential energy  = ?

Solution:

The elastic potential energy of a body is the energy stored within an elastic string.

  EPE  = k e²

k is the spring constant

e is the extension

 Now;

      EPE  =    x 500 x 1²   = 250J
