Homework Help: Physics

Posted by Jim on Tuesday, April 24, 2007 at 12:21am.

Can someone please provide me with some insight on this question?

A pair of scissors is being used to cut a string. Does each blade of the scissors have the same angular velocity (both magnitude and direction) at a given instant?
yes
no
Give your reasoning.


The answer is no. If both blades' magnitude and direction were the same, the blades would not close and the scissors would not cut. They would rotate tgether.
