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, r = 1 km = 1000 m

Speed of the aircraft, v = 900 km/h = 900 × 5 / 18  =  250 m/s

Centripetal acceleration,

Acceleration due to gravity, g = 9.8 m/s2

Therefore,

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