A delivery drone operates along an east–west straight line and follows these four consecutive stages starting from point A:
Stage A: Flies 800m due east at a steady speed of 10ms−1.
Stage B: Hovers (remains stationary) for 40s to unload a parcel.
Stage C: Flies 300m due west at 5ms−1.
Stage D: Flies 700m due east at 20ms−1 and stops at point B.
Answer the following:
(a) Calculate the time taken in each of the three flying stages.
(b) Find the total distance travelled by the drone and its final displacement from point A.
(c) Determine the total time for the entire operation, including the hovering period.
(d) Compute (i) the average speed and (ii) the magnitude of the average velocity of the drone for the complete trip from A to B.
