Homework Help: Physics(please check)

Posted by Hannah on Tuesday, June 5, 2012 at 11:44am.

A 53-N crate is suspended from the left end of a plank. The plank weighs 21 N, but it is not uniform, so its center of gravity does not lie halfway between the two ends. The system is balanced by a support that is 0.30 m from the left end of the plank. How far to the right of the support is the plank’s center of gravity?

I did (53)(0.30) + (21)(0.30) / 53+21

Is this correct?
