Answer 1

A girl stands on a moving sidewalk (conveyor belt) that is moving to
the right at a speed of \(\color{black}{\rm 2 m/s}\) relative to the ground. \(\tiny~\)A dog runs on
the belt toward the girl at a speed of \(\color{black}{\rm 8 m/s}\) relative to the belt.



\( \rm What~is~the ~speed ~of ~the ~dog ~relative ~to ~the ~ground?\)
