Problem

A swimmer pushes the water backward with a steady horizontal force of 60 N60\,\text{N}. The water offers a resistive force of 50 N50\,\text{N} opposite to the motion. Which option correctly states the net horizontal force on the swimmer and the resulting acceleration? (a) 0 N0\,\text{N}; moves with uniform velocity (b) 110 N110\,\text{N} backward; decelerates backward (c) 10 N10\,\text{N} forward; accelerates forward (d) 10 N10\,\text{N} backward; decelerates
