Bouncing Ball Problem Intense Question

Need some help here please..

A ball is dropped from 1m from inside the elevator. The ball returns to 80% of it's previous height... This is where it gets complicated. Imagine there is a glass elevator that moves up at a constant speed of 5 m/s. Assume the ball is dropped at the instant the elevator starts raising. Draw a graph to show the height of the ball above the ground as a function of time. I don't need a graph I need an explanation as to how to tackle this problem. Please halp. Thanks..

Just take the ball bouncing without moving, then taking the ball moving up the elevator without bouncing, then combine them.

[quote=ShiverStar]Do you know how to solve the problem without the elevator aspect, i.e. a convergent sum? The only difference now is that the usual graph is adjusted along the linear ascension of the elevator.[/quote]

I've solved it without the elevator aspect. But the thing is each bounce to the ground will change because the ground changes in between each point. Ahh so confusing.

This is Basil so your chances of getting a serious answer is quite low. Do what the other guy said search for a mathematics forum.
