## Answers

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
