Question

An elastic band has been stretched 0.9m from its equilibrium position. The spring constant of the elastic band is 20.5N/m calculate its elastic potentiometer energy store

Answer 1

The elastic potential energy stored in the elastic band can be calculated using the formula:

Elastic Potential Energy = 0.5 x Spring Constant x (Extension)^2

where the spring constant is 20.5 N/m and the extension is 0.9 m.

Plugging in the values, we get:

Elastic Potential Energy = 0.5 x 20.5 N/m x (0.9 m)^2 = 8.29 J

Therefore, the elastic potential energy stored in the elastic band is 8.29 Joules.
