An aircraft in a steady level flight at forward speed of 50 m/s suddenly rolls by 180o and becomes
inverted. If no other changes are made to the configuration or controls of the aircraft, the nature of
the subsequent flight path taken by the aircraft and its characteristic parameter(s) (assume g=9.81
ms-2) are
A
straight line path with a speed of 50 m/s
B
upward circular path with a speed of 50 m/s and radius of 127.4 m
C
downward circular path with a speed of 50 m/s and radius of 127.4 m/s
D
downward circular path with a speed of 25 m/s and radius of 254.8 m/s

Correct : c
