given the airplane is flying at a constant altitude
radius of circular path, r = 3380 m
time taken to complete one half of a circle, T = 148 s
a. in the given time, the airplane covers half the circel to displacement
d = 2*r = 6760 m
b. average velocity during the given time = d/T
Vav = 6760/148 = 45.675 m/s
c. average speed = pi*r/T
v = pi*3380/148 = 71.747 m/s
