Part 2: The pilot lands the drone in order to change the battery. During take-off, the drone's

position as a function of time is now given by:

(e) Find the gradient of the air temperature.

(f) Find the rate of change of air temperature in the direction of travel of the drone as a function of time.

(g) Find the curl of the total force vector. Is this vector function irrotational?

(h) What is the work done on the drone by the wind force, Fw, between t = 5 and t = 10 seconds?
