QUESTION:

(II) When a high jumper is in a position such that his arms and legs are hanging vertically, and his trunk and head are horizontal, calculate how far below the torso's median line the  will be. Will this  be outside the body? Use Table .

ANSWER:

We have to determine whether the location of the center of mass of the high jumper with the data and situation mentioned in the problem is outside the body or not.

Step 1 of 4

Concept:

Center of mass(CM) of a body is an imaginary point at which the whole mass of the body is supposed to be concentrated. We consider that the net force acts on the center of mass of the body, instead of considering that it acts on each and every point on the body for simpler calculation and this is one of the importance of the application of CM.
