Problem

A pedestrian starts from the origin O of an

x

–

y

coordinate grid. After walking for

5\,\text{s}

, the pedestrian reaches point P whose coordinates are

(3\,\text{m},\;4\,\text{m})

. (i) Calculate the magnitude of the displacement OP. (ii) Determine the direction of OP measured as the angle it makes with the positive

x

-axis. (iii) Using your results, find the magnitude and direction of the pedestrian’s average velocity for the

5\,\text{s}

interval.
