How can i solve velocity of dropping object if i know only distance it has dropped and i don't know how long it took or weight of the object.

So i have this graph about Bungee jumping and graph starts after the rope starts to stretch and at that point timer starts and at that point t/s is 0..

I need to know velocity of the guy at t/s 0 and i don't have any other information than when t/s is 0 guys has dropped 18meters.

It was bit hard to explain but i hope someone understood.

Sorry for bad english

edit: i only know that he dropped 18meters but not how long it took.

assumed under simple initial conditions, you just have acceleration of 9.8m/s/s. in your case, it is probably expected for you to just plug into an equation. equation relating accel, distance, velocity
