Question
A high jumper successfully clears the bar. Is it possible that his centre of mass crossed the bar from below it? Try it with appropriate figures.
✓

Answer

The the man jumps over bar the shape of the body is like semicircle so the center of mass lies near about the center of the semicircle of the body of high jumper. if jumper just clears the bar it is possible that his center of mass may lie below bar.
