8. 

The boys A, B and C stand near the edges of a raft as shown. Determine the location (x, y) of boy D so that all four boys create a single resultant force acting through the raft's center O. Provided the raft itself is symmetric, this would keep the raft afloat in a horizontal plane. the mass of each boy is indicated in the diagram.

[A]. x = 4.5 m, y = 1.5 m
[B]. x = 3.0 m, y = 3.0 m
[C]. x = 1.5 m, y = 4.5 m
[D]. x = 3.0 m, y = 4.0 m

Answer: Option C
