Usually, the drawbridge is lowered to a horizontal position so that the end of the bridge rests on the stone ledge. Unfortunately, Lost-a-Lot's squire didn't lower the drawbridge far enough and stopped it at e = 20.0° above the horizontal. The knight and his horse stop when their combined center of mass is d = 1.25 m from the end of the bridge. The uniform bridge is { = 7.25 m long and has mass 2 500 kg. The lift cable is attached to the bridge 5.00 m from the hinge at the castle end and to a point on the castle wall h = 12.0 m above the bridge. Lost-a-Lot's mass combined with his armor and steed is 1 070 kg. While Lost-a-Lot ponders his next move, the enemy attacks! An incoming projectile breaks off the stone ledge so that the end of the drawbridge can be lowered past the wall where it usually rests. In addition, a fragment of the projectile bounces up and cuts the drawbridge cable! The…arrow_forwardA uniform ladder rests against a smooth vertical wall and on a rough horizontal ground.
