A spring has a spring constant of 53N/m. How much elastic potential energy is stored in the spring in the spring when it is compressed by p. 21 m?

Answer:11686.5 joules

Explanation:

elastic constant (k) = 53N/m

extension (e) = 21m

Elastic potential energy = (k x e^2) / 2

Elastic potential energy = (53 x (21) ^2) / 2

Elastic potential energy = (53x21x21) / 2

Elastic potential energy=23373/2

Elastic potential energy=11686.5

Elastic potential energy is 11686.5 joules
