In Part 1 of the lab activity, you did not assume that the center of mass was at the 50 cm mark. Instead, you determined the location of the center of mass of the meter stick to eliminate this source of error. Let's say that the actual center of mass is at the 49 cm mark. If you did not measure this and assumed it was at 50 cm, what kind of error would have been introduced
