Answer:

0.275J

Step-by-step explanation:

Given parameters:

Extension = 0.5m

Spring coefficient = 2.2N/m

Unknown:

Energy stored in the rubberband = ?

Solution:

The elastic potential energy is given as:

Elastic potential energy =
(1)/(2) k e²

k is the spring constant

e is the extension

Elastic potential energy =
(1)/(2) x 2.2 x 0.5² = 0.275J
