Need formula height of diver off springboard

[Rbraind]

Homework Statement

two divers jump on a diving board, who will jump highest, Weights of divers are known and velocity they are jumping at. I'm stuck finding the right formula, I know the board has to deform, stored energy has an influenece. I think its a basic question but my brain has frozen,any help really appreciated. thanx

Welcome to PF!As far as I can see, the problems hasn't got anything to do with energy stored in the spring because you are already told about the velocity of take-off for the diver. Of course, in a general sense, you would consider the diver jumping upwards with that velocity, which, thereafter makes it a simple linear kinematics problem!

THANKYOU! thanxs for the quick reply and push in the right direction.. I was definitely making it more complicated than it actually was - cheers
