Problem

A swimmer pushes the water backward with a steady horizontal force of

60\,\text{N}

. The water offers a resistive force of

50\,\text{N}

opposite to the motion. Which option correctly states the net horizontal force on the swimmer and the resulting acceleration? a)

0\,\text{N}

; moves with uniform velocity b)

110\,\text{N}

backward; decelerates backward c)

10\,\text{N}

forward; accelerates forward d)

10\,\text{N}

backward; decelerates
