Homework Statement
Hey guys.
So I got this disk connected to a spring which is connected to a wall.
A mass m hits the disk with a velocity v and sticks to it.
The question is to find the velocity of m at point A.
As you can see I used the conservation of the angular momentum to find [tex]\omega[/tex] at the beginning.
The thing I'm not sure about is the energy conservation equation I wrote there, I'm not sure about the gravitational potential energy, I mean, is this right?
