The energy stored in a spring is elastic potential energy. The formula for calculating the elastic potential energy is expressed as

elastic potential energy = 1/2kx^2

where

k represents spring constant

x represents the distance through which the spring was compressed

From the information given,

k = 150 N/m

x = 2cm

we would convert 2cm to m

recall, 100cm = 1 m

2 cm = 2/100 = 0.02 m

By substituting these values into the formula,

elastic potential energy = 1/2 x 150 x 0.02^2

elastic potential energy = 0.03 J
