A pedestrian starts from the origin O of an x–y coordinate grid. After walking for 5s, the pedestrian reaches point P whose coordinates are (3m,4m).
a. (i) Calculate the magnitude of the displacement OP.
b. (ii) Determine the direction of OP measured as the angle it makes with the positive x-axis.
c. (iii) Using your results, find the magnitude and direction of the pedestrian’s average velocity for the 5s interval.
