# M2 Centre of mass question watch

1. https://onedrive.live.com/redir?resi...hint=folder%2c

Not sure how to do part B - I got tan^-1(1/3) or 18.4 degrees for part A (unrelated)

I show my method of part B but I doubt it's correct, does the x-coordinate of point C have anything to do with the "new centre of mass"? (it has to be 10 y-coordinates up instead of 15 when adding "m" I think).

Hopefully someone can help -
