Problem

A drone starts from point

A

and flies

1200\,\text{m}

due north at a steady speed of

5\,\text{m s}^{-1}

to reach point

B

. It immediately turns back and flies

600\,\text{m}

toward point

A

at a speed of

10\,\text{m s}^{-1}

to reach point

C

. It then hovers at point

C

for

30\,\text{s}

before its motors are switched off. a. (a) Calculate the total time taken from the start at

A

until the motors are switched off. b. (b) Find the total distance travelled by the drone during this period. c. (c) Determine the displacement (magnitude and direction) of the drone from point

A

to point

C

. d. (d) Using your results, compute (i) the average speed and (ii) the average velocity of the drone for the complete motion described.
