Make a fruit fall from a tree, bounce a few times and then lie still

Shaking a tree should drop fruit that hits the ground and hops. With a naive bounce the fruit keeps trembling on the ground forever with tiny hops, or sinks into the floor, or never settles at all. Here is a bounce with a clear end that is exact at any frame rate.

Why this works

Every bounce keeps a fixed share of the speed, so each hop is smaller and shorter than the last and the whole thing must end. Knowing the end in advance means no jitter at the floor and the same result on any device.

When not to use it

Not when the fruit can be pushed, rolls down a slope or hits other things on the way. A fixed fall only knows the straight drop to flat ground, so let a real physics step run there.
