Question

6. A spring has a stiffness constant of 100 N m-1
. Find the potential energy stored in the

spring when it is compressed by 1 cm.​

Answer 1

Answer:

A spring has a stiffness constant of 100 N m-1

it is compressed by 1 cm

Answer 2

Answer:

Potential energy of spring with stiffness constant k = 100 N/m, and compression x = 1 cm = 1/100 m is given by:

U = 1/2 kx² = 1/2 * 100 * 1/100 * 1/100 = 1/200 = 0.005 J
