Answer:

0.81 m

Explanation:

K= 36 N/m

θ= 30°

mass m = 8 kg

let the distance moved by the box be d

We can  solve this using

Apply conservation of energy

[tex]\frac{1}{2}kx^2= mg sin\theta\times d[/tex]

d= 1/2×k×x^2/ mg sinθ

[tex]d= \frac{1}{2}\times36(0.042)^2/8\times9.81sin30[/tex]

d  = 0.81 m
