VIDEO TRANSCRIPT
This is Giancoli Answers with Mr. Dychko. The table 7–1 gives us the percent mass of your upper leg and the lower leg so add them together to get the total leg not including the feet. And this is for both legs combined so the mass of one leg is gonna be a half of this percent—31.1 percent— and times the total mass of the person's body. So let's say the person is 95 kilograms times a half times 31.1 out of a 100 that gives about 15 kilograms of mass in the legs.
