This is probably a real easy problem but I can not get this problem right for my life, so would someone please help me out here :redface:
A 9m beam of mass 300 kg extends over a ledge, the beam is not attatched, but simply rests on the surface. A 75 kg student intends to position the beam so that he can walk to the end of it. Hwo far from the edge of the ledge can the beam extend?
