A hiker walks 4.0km due north in 50min, then changes direction and walks 3.0km due east in 40min. He rests for 10min and finally walks 2.0km due south in 20min before setting up camp.
(a) Compute the total distance travelled and the total time taken.
(b) Determine the magnitude and direction of the resultant displacement from the starting point to the campsite.
(c) Calculate the average speed and the average velocity for the entire excursion.
(d) Based on your results, classify average speed and average velocity as scalar or vector quantities, giving reasons.
