Homework Statement
The forearm (including the hand) has a mass of 4.26 kg. The upper arm exerts the force of 14 N on the forearm. If the forearm has an acceleration of 2.54 m/s^2, determine the mass of the object being pulled by the hand. (Assume the object slides over a frictionless surface.)
Homework Equations
Newton's Second Law:
Fnet=ma
The Attempt at a Solution
So I have my free bodies. With the arm, I have the three forces of Normal, Tension, and Mass, and with the object, the same three forces. I don't know if these are right so that might be why I'm stuck.
Assuming that those free bodies are right, I am unsure of what equations (Newton's Second Law) to write down and use or what approach to take towards this problem.
Any Help Would Be Great
