If a seagull drops a shell from rest at a height of 12 m how fast is the shell moving when it hits the rocks

As seagull drops a shell from rest at a height of 12 m, so we use kinematic equation of motion,

Here, h is the height, u is initial velocity , v is final velocity and g is acceleration due to gravity.

Given,  h = 12 m.

We take, and because seagull drops a  shell from rest.

Therefore, the speed of shell when it hits the rocks,

like poles repel so keep pushing north to north and repels funny to see this
