Assume you are given two objects whose centre of mass is located exactly at the origin. The first object has a mass of 33 kg and is located at position +30 m with respect to the origin. If the mass of the second object is 7.0 kg, what is its position (in m) with respect to the origin? (Include the sign if the answer is negative, and no sign if the answer is positive.)
