Urgent Physics help!!

Hi I’m really struggling to answer these physics questions as I don’t know how to calculate an increase in energy store
Thanks in advance
I will attach it down below 👇

You literally just need to apply the energy formulae from the data and formula booklet

change in gravitational potential energy = mgΔh
amount of kinetic energy = 1/2mv2
amount of spring potential energy = 1/2kx2
