Pulley question(Newtons third law)

[Jennifer001]

Homework Statement

there is a pulley and on one side there's a man hanging on it he weights 60kg on the other side resting on the ground is a 100kg weight. what is the tension on the rope

Homework Equations

T-m1g=m1a
T-m2g=m2a
F=2T-(m1+m2)g

The Attempt at a Solution

T-m1g=m1a T-m2g=m2a
T=m1a+m1g T=m2a+m2g
m1a+m1g=m2a+m2g

then i pulled in the numbers and got
g=a which = 9.8 (gravity)

and now I am stuck.. i think i might have done somethign wrong can someone help?

Hi Jennifer001! Welcome to PF!

Hint: the man is hanging … stationary … so a = 0.
