A point mass, m, is attached to one end of a light inextensible string of length 5r with
the other end being fi
xed at (0; 0; 3r), rotates in a circle with an angular frequency
w (omega) about the z-axis: Calculate its linear velocity and its angular momentum when
the mass is at (4r; 3r; 3r) and at (-4r;-3r; 3r)
Please could someone help me do this question? I have no idea where to start and I have a university exam tomorrow
All I know is that tangential velocity= omega x r but I'm not sure how I can use that here
