A man is stranded on a raft (mass of man and raft = 1300 kg), as shown in the figure. By paddling, he causes an average force ?⃗ of 17 N to be applied to the raft in a direction due east (the +x direction). The wind also exerts a force ? on the raft. This force has a magnitude of 15 N and points 67° north of east. Ignoring any resistance from the water, find the x and y components of the raft’s acceleration.
