## Question:

The barge B has weight ${ W }_{ B }$ and supports an automobile weighing ${ W }_{ a }$. If the barge is not tied to the pier P and someone drives the automobile to the other side of the barge for unloading, determine how far the barge moves away from the pier. Neglect the resistance of the water.Given: ${ W }_{ B }$= 30000 lb , ${ W }_{ a }$ = 3000 lb , d = 200 ft , g = ${ 32.2ft/s }^{ 2 }$
