Answer:To calculate the elastic potential energy stored in the spring, we can use the formula:
Elastic potential energy = (1/2) * k * Δx^2
where k is the force constant of the spring and Δx is the change in length from the relaxed length.
First, we need to calculate Δx:
Δx = 3.50 m - 2.58 m
Δx = 0.92 m
Now, we can calculate the elastic potential energy:
Elastic potential energy = (1/2) * k * Δx^2
Elastic potential energy = (1/2) * 5.2 N/m * (0.92 m)^2
Elastic potential energy = 2.17 J
Therefore, the elastic potential energy stored in the spring is 2.17 J.
