Question

1. A 165 pound football player assumed a 4 point stance at the line. If his base of support was 30” wide, 38” deep, with the center of gravity 28” off the ground and 16” from the front edge of the base of support, how many inch-pounds would be required to move his center of gravity outside his base of support from a 1) frontal attack, 2) from the side, & 3) from the rear?

Can you please include a picture for the problem?
