Question

A spring with a constant of 92N/m is compressed 2.8 cm. How much potential energy is stored in the spring?

Answer 1

Answer:

0.036J

Explanation:

Given parameters:

Spring constant , K  = 92N/m

Compression  = 2.8cm  = 0.028m

Unknown:

Potential energy  = ?

Solution:

To solve this problem;

          P.E  =$\frac{1}{2}$ K e²

 K is the spring constant

 e is the compression

so;

      P.E = $\frac{1}{2}$  x 92 x 0.028²  = 0.036J
