I'm slightly confused with the directionality of a pulley problem from Kaplan. The problem is:
In the pulley system shown, what is the tension force in each rope?
m=10kg
Object is accelerating up at 2 m/s2.
I have attached a rough sketch below.
I began to solve it with: Sum of forces = 2T - mg = ma
My question is, is g supposed to be negative because Kaplan is giving an answer of 60N and I'm getting 4oN. This discrepancy is based on the sign given to gravity and whether to add or subtract a and g.
