- A meter stick has a mass of 0.30 kg and balances at its center. When a small chain is suspended from one end, the balance point moves 12.0 cm toward the end with the chain. Determine the mass of the chain. 0 x Determine a convenient place for the origin of the coordinate system. See if you can write an expression for the center of mass of the two objects in terms of known quantities and the mass of the chain and then solve for the mass of the chain. g Submit AnswerView Policies Current Attempt in Progress The velocity of a 6 kg particle is given by = (6t î+ 2t² ĵ) m/s, with time t in seconds.
