Question: A S e = 8.14 -+ BI0 Bone Fracture. Experimental tests have shown that bone will rupture if it is subjected to a force density

A S e = 8.14 -+ BI0 Bone Fracture. Experimental tests have shown that bone will rupture if it is subjected to a force density of 1.03 X 108 N/m?. Suppose a 70.0-kg person carelessly roller- skates into an overhead metal beam that hits his forehead and com- pletely stops his forward motion. If the area of contact with the person's forehead is 1.5 cm?, what is the greatest speed with which ~ he can hit the wall without breaking any bone if his head is in con- tact with the beam for 10.0 ms?
