Physics AQA A level: If a spring was held down with a mass attached to the bottom and attached to a firm surface at the other
Then let go to allow it to beoing up and down

What would be the spring potential
What would be the gravitational potential energy
What would be the kinetic energies of the spring
When the spring was at the very top of its motion
And can you explain why

The spring is stretched the least, so, the potential energy of the spring is at a minimum.

The mass is lifted as high as it will go, so, the potential energy due to gravity is at a maximum.

The mass is stopped, so, its kinetic energy is zero
