A mass is attached to the lower end of a vertical light inelastic string. The mass is given a horizontal velocity of 5 ms-1.

what is the greatest height of the mass?

I tried drawing a diagram but it didnt seem to help, I just dont know how to approach this at all?

Conservation of energy would be the obvious way to do it, so KE+GPE.
I tried that and it didn’t seem to work

Post what you tried / why you think it doesnt work?

Have you tried "Loss in KE = Gain in GPE"?
