A man is paddling a raft, as in Examples 2 and 3.

The free-body diagram shows the forces and that act on the raft. Forces acting on the raft in a direction perpendicular to the surface of the water play no role in the examples and are omitted for clarity.
(c)  
The raft's acceleration components ax and ay.
(d)  
In 65 s, the components of the raft's displacement are x = 48 m and y = 23 m.
