Question
A painter's plank is suspended horizontally either end byropes and in mechanical equilibrium. A person standing in themiddle weighs 250 N and tension on each rope is 500 N. 1. Is it correct to say that the WEIGHT of the staging is (500+ 500) + -250 = 750 N? 2. Also, what is the MASS of the staging? I understand that weight is the effect of gravity on anobject, and that mass is the density of an object. I'm just notsure how to address the second question. Many thanks in advance.

2. Also, what is the MASS of the staging?
mass=weight/acceleration due to gravity=750/9.8=76.53kg
