1. SO the debate is if a hamster was running at its fastest speed, how many times could it make it round a play wheel before it falls from the top.

This is the video we were watching that gave us the idea. Were trying to work out if someone is pushing the wheel round from the top, about halfway into the video when the hamster sticks to the wall of the wheel and keeps on spinning.

I know it has a lot to do with the friction of the wheel, which we cannot find out.
but we are considering these values:

V(max) = 3.13ms-1
mass = 0.03kg
height of the wheel = 15cm

This is revision procrastination at its finest but i guess its better than ps4, and theres a 10er stake..

In the video the hamster makes 8 rotations before falling from the top, incase you don't want to see the video. Is this possible without an external force pushing it??
2. RIP hamster friend
