Hi all, I thought of an interesting problem that I don't know how to approach (it's been 8 years since my last physics class in undergrad studies).
Here is a crude depiction of the problem:
_____■_____ _____●_____ lever
....↑....... ground
Assume the cube and sphere (obviously depicted here as a square and circle, respectively) have equal mass and are equidistant from the fulcrum, so that the lever is in a state of equilibrium.
Now suppose that some additional external stimulus acts upon the sphere to disrupt the equilibrium such the sphere begins to roll down the lever.
How would I calculate how long it would take the the circle to reach the ground and its terminal velocity when it hits the ground?
There must be some differential equation(s) that describes the system.
Thanks for any insight you can offer.
