A car is driven first straight north for 30km in 0.50h and then straight east for 40km in 0.80h.
a. (i) Calculate the total distance covered and the magnitude of the net displacement for the entire trip.
b. (ii) Determine the average speed and the magnitude of the average velocity for the trip.
c. (iii) State which of the two magnitudes—average speed or average velocity—is larger in this case and give a reason.
