At an airport, luggage is unloaded from a plane into threecars of a luggage carrier. The acceleration of the carrier is $$\displaystyle{0.12}\frac{{m}}{{s}^{{{2}}}}$$, and friction is negligible. The coupling bars havenegligible mass. By how much would the tension in each of thecoupling bars A,B, and C change if 39kg of luggage were removedfrom car 2 and placed in (a) car 1 and (b) car 3? If the tensionchanges, specify whether it increases or decreases.
