Calculating the Stiffness of the Spring

To calculate the stiffness of the spring, we can use the formula for potential energy stored in a deformed elastic body:

Potential Energy (U) = (1/2) * k * x^2

Where: - U = potential energy - k = stiffness of the spring - x = deformation of the spring

Given that the potential energy of the deformed body is 40 J and the deformation of the spring is 40 cm (or 0.4 m), we can use the formula to calculate the stiffness of the spring.

Stiffness (k) = 2 * U / x^2

Substituting the given values: Stiffness (k) = 2 * 40 J / (0.4 m)^2

Calculating the stiffness: Stiffness (k) = 2 * 40 J / 0.16 m^2 = 500 N/m

Therefore, the stiffness of the spring is 500 N/m.

This calculation is based on the formula for potential energy stored in a deformed elastic body and the given values of potential energy and deformation of the spring
