An aircraft executes a horizontal loop of radius 1.00 km with a steady speed of 900
km/h. Compare its centripetal acceleration with the acceleration due to gravity

Radius of the loop,Â rÂ = 1 km = 1000 mÂ

Speed of the aircraft,Â vÂ = 900 km/h = 900Â Ã—Â 5 / 18Â  =Â  250 m/s

Centripetal acceleration,Â
=Â

Acceleration due to gravity,Â gÂ = 9.8 m/s2

Therefore,Â

acÂ / g = 62.5 / 9.8Â  =Â  6.38
acÂ = 6.38 g, is the required centripetal acceleration.Â
