Sam performs an experiment to test which goes farther when thrown, a golf ball or a baseball. He throws a golf ball from a height of 10 meters and measures how far it goes with a metric measuring tape. He then throws a baseball from a height of 10 meters and measures how far it goes with a metric measurement tape. He is worried that his measurements may not be accurate.

A. measured with a ruler



B. performed multiple trials



C. used different drop heights for both



D. chosen a shorter drop height for both
