an aircraft executes a horizontal loop of radius 1 km with a speed of 900 km/h.compare its centripetal acceleration with the acceleration due to gravity.
Asked by | 22nd Jul, 2010, 07:42: PM
V = 900 km/h = 250 m/s
R = 1 km = 1000 m
Centripetal acceleration = V2/R = 62.5 m/s2
Acceleration due to gravity = 10 m/s2
Centripetal acceleration/Acceleration due to gravity = 6.25
The centripetal acceleration is 6.25 times acceleration due to gravity.
