Explanation / Answer

here,

mass , m = 5 kg

theta = 30 degree

d = 1.3 m

spring constant , K = 3000 N/m

let the compression in the spring be x

work done by gravity = potential energy gained by spring

m * g * (d + x) * sin(theta) = 0.5 * k * x^2

5 * 9.81 * ( 1.3 + x) * sin(30) = 0.5 * 3000 * x^2

solving for x

x = 0.15 m

the compression in the spring is 0.15 m
