Question

A block of mass m is released from rest with spring at it's natural length. Find the maximum elongation in the spring.​

Answer 1

$w.all \: forces = kinetic \: energy \\ w.gravity + w.spring = kinetic \: energy \\ \\ mg(x) - \frac{1}{2}k( {x}^{2} - 0 ) = 0 \\ mg(x) = \frac{1}{2} k {x}^{2} \\ x = \frac{2mg}{k} \\ \\ thank \: you$
