One revolution also corresponds to an angular displacement of 2π rad.
So, the angular velocity is
120 rev/min = (120 rev/min) * (2π rad/rev) = 240π rad/min
i believe it is 645, 500 !
A delightful question.
I think I have it.
The number is 22 .
Its factors are 1, 2, 11, and 22 .
The rectangle on the right is 81 and the rectangle on the left is 24. I don't really know about the second one sorry, but I hope this helped.
