Homework Help: Physics

A 5.00-kg object placed on a frictionless, horizontal table is connected to a cable that passes over a pulley and then is fastened to a hanging 9.00-kg object. Draw free-body diagrams of both objects. Find the acceleration of the two objects and the tension in the string.

Ignore the pulley's moment of inertia (since they don't tell you its radius and mass). Let T be the unknown tension on both sides.

With two equations, the variable T can be eliminated to solve for the acceleration, which is the same for both masses.

We are eager to critique your work and provide further assistance if you get stuck. You need the exercise in doing Free Body Diagrams yourself
