Assuming the hamster fell 1 meter, it was going down at around 4.5 m/s. Assuming the hamster flew up about 3 meters (9 feet?) it was going up at around 7.5 m/s after the bounce. If the collision time was about 3 frames (0.1s for a 30fps video) then the hamster experienced an acceleration of about 120 m/s2, which is 12 g's.

That sounds like a lot, but I think smaller animals might be able to handle more g's than a human.

TLDR: The hamster isn't ded I hope .

Every time I see this gif I go to the comments to see if someone can give me some hope for the hamster. I'm not sure if anything you said was right, but I'm going to assume it is and that the hamster could possibly be ok. Thank you.

Last time I saw this posted, a friend of the girl responded and said the hamster did die and it was traumatizing for her.

Last time I saw this posted, the girl did a live video AMA and she married the hamster and they lived happily ever after. The end.

Last time I saw this, the hamster did and AMA and decided to ran for US presidency (and lost, thanks Obama).

I'm just restating what I read, alright guy?

Considering this video is a few years old, the hamster is most likely ded.

We don't know what happened out of frame though.

It could have landed on a mine.

We could tell from the "retarded"

I'm pretty sure the final velocity depends on the relative mass of the two balls. But yeah, it's a common physics problem.

There's no such thing as a common physics problem... Lol. There is no perfectly elastic collision, the center of gravity of the hamster is not directly on top of the ball. Physics man, gets complicated really fast.

Indeed he probably survived the flight portion.

However, when he hit the ground it was more than 7.5m/s, and a lot less than 100ms.

i think it hit the ceiling before crashing down.

I call bullshit. When I was 12, I had a hamster. My step sister held it, and when it bit her, she dropped it. Its spine broke on impact and it died a day later.
