Sir Lancelot rides slowly out of the castle at Camelot and onto the 12.0-m-long drawbridge that passes over the moat ( Fig. P11.44 ). Unbeknownst to him, his enemies have partially severed the vertical cable holding up the front end of the bridge so that it will break under a tension of 5.80 × l0 3 N. The bridge has mass 200 kg and its center of gravity is at its center. Lancelot, his lance, his armor, and his horse together have a combined mass of 600 kg. Will the cable break before Lancelot reaches the end of the drawbridge? If so, how far from the castle end of the bridge will the center of gravity of the horse plus rider be when the cable breaks?

Sir Lancelot rides slowly out of the castle at Camelot and
onto the 12.0-m-long drawbridge that passes over the moat
(Figure 1). Unbeknownst to him, his enemies have partially
severed the vertical cable holding up the front end of the
bridge so that it will break under a tension of 5.80 x 103 N.
The bridge has mass 200 kg and its center of gravity is at its
center. Lancelot, his lance, his armor, and his horse together
have a combined mass of 600 kg.
