I dunno but they seem to survive impact relatively unscathed on a fairly regular basis. I don't know how fast they're actually going when they hit the ground. They're of course hollow (and presumably empty by then) and from what I'd read a while back, made of titanium which weighs about half as much as steel.
According to a November analysis by the European Space Agency (ESA), the spacecraft's orbit"will inevitably decay sometime between January and March 2018, when it will make an uncontrolled reentry." "Even a couple of days before it re-enterswe probably won't know better than six or seven hours, plus or minus, when it's going to come down," Harvard astrophysicist Jonathan McDowell told The Guardian in 2016. "Not knowing when it's going to come down translates as not knowing where its going to come down."

just taking a guess id say they are slowed to terminal velocity before they hit the ground. u could probly drop one from 1000 feet and the impact would be no different id imagine.
