You are about to do a back squat. You place a 20 kg plate on one end of the bar and mistakenly place a 40 kg plate on the other end of the bar. The bar is 2 m long and has a mass of 20 kg without the plates on it. The 20 kg plate is located 0.4 m from the left end of the bar and the 40 kg plate is located 0.4 m from the right end of the bar. How far (m) from the right end of the bar is the center of gravity located?
