A spring with constant 559 N/m is 0.14 meters long when not stretched or compressed. You compress the spring until it is 0.07 meters long. How many joules of elastic potential energy are stored in the compressed spring

Answer:

1.46755 Joules

Explanation:

Applying,

E = 1/2ke²......................... Equation 1

Where E = Elastic potential energy of the spring, k = spring constant, e = extension

From the question,

Gieven: k = 559 N/m, e = (0.14-0.07) meters = 0.07 meters

Substitute these values into equation 1

E = 1/2(599×0.07²)

E = 2.9351/2

E = 1.46755 Joules
