Question: Experimental tests have shown that bone will rupture if it is subjected to a force density of 1.03 10 8 N/m 2 . Suppose

Experimental tests have shown that bone will rupture if it is subjected to a force density of 1.03 × 10⁸ N/m². Suppose a 70.0-kg person carelessly rollerskates into an overhead metal beam that hits his forehead and completely stops his forward motion. If the area of contact with the person’s forehead is 1.5 cm², what is the greatest speed with which he can hit the wall without breaking any bone if his head is in contact with the beam for 10.0 ms?
