Problem

A sled is pulled by a rope so that the rope exerts a force of

\vec{F}_{r\to s}=5\,\hat{i}+12\,\hat{j}\,\text{N}

on the sled. What are (i) the force exerted by the sled on the rope and (ii) its magnitude? a)

5\,\hat{i}+12\,\hat{j}\;\text{N};\;13\,\text{N}

-5\,\hat{i}-12\,\hat{j}\;\text{N};\;17\,\text{N}

-5\,\hat{i}-12\,\hat{j}\;\text{N};\;13\,\text{N}

-5\,\hat{i}+12\,\hat{j}\;\text{N};\;13\,\text{N}
