This problem is about what happens to the center of mass of two people standing on a frictionless surface and they push away from one another.

In part one of this INET interview, John Kay suggests that consistency and rigor have become the requirements of modern economics. However, these requirements have forced economists to use only deductive reasoning to remain the pretense...

Mass 1 and mass 2 hang from either side of a frictionless #pulley with #rotationalInertia, I, and radius, R. What is the angular acceleration of the pulley? Use #ConservationOfEnergy

You're really getting good at building physics toys in your garage! Check this awesome pulley system. You put your physics knowledge to the test and try to make a prediction about what will happen when you let these two blocks go. Will...

If a pulley is in static equilibrium and the following is true:

1) Rope is mas
sless
2) Pin is fr

ictionless

Then the tension in the cable will be constant everywh

ere along the cable.

There is only 1 force...
