Question

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 1

Answer:11686.5 joules

Step-by-step 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
