Two masses hanging from a pulley (video) Khan Academy
Here I m just solving for the magnitude of the tension anyway. So if I solve this if I plug this into the calculator and solve for tension I m gonna get 36.75 Newtons which is less than the force of gravity which it has to be cause if the tension was greater than the force of gravity this five kilogram mass would accelerate up.
