Question

if tim walks to the mailbox 600 m south and then to his neighbor's house 300 m north and the entire trip takes him 5 minutes, then what is his average velocity?

Answer 1

The average velocity is -60 m per sec south. or -60 ms⁻¹ j

velocity is the directional velocity of an object in motion as a demonstration of its rate of change in function as found from a particular body of reference and as measured by a selected trend of the time. common speed is described because of the alternate in function or displacement divided by the time durations wherein the displacement occurs. The common pace may be wonderful or poor depending upon the sign of the displacement.

Let The direction of the south is downward = - X

And north direction +X from origin.

   So, Tim walks to the mailbox 600 m south from origin = -600

Then to his neighbor's house 300 m north = +300

Total time of the journey = 5 minutes

    Total displace ment = -600 + 300

                                      = - 300 south

Average velocity = total displacement/total time taken

                             = -300/5

                            = -60 m per sec south.
