Problem

A rowboat of mass

150\,\text{kg}

experiences a backward force of

180\,\text{N}

from the oars on the water. If the water offers a resistive force of

60\,\text{N}

opposite to the boat’s motion, find the boat’s acceleration. a)

0.4\,\text{m}\,\text{s}^{-2}

0.8\,\text{m}\,\text{s}^{-2}

0.6\,\text{m}\,\text{s}^{-2}

1.2\,\text{m}\,\text{s}^{-2}
