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.


Given:


Radius of the horizontal loop = r = 1 km = 1000m


Speed of the aircraft = v = 900 km/hr


= 250 m/s


= 62.5 m/s2


Acceleration due to gravity = g= 9.8 m/s2


ac/g = 62.5/9.8 = 6.38


Ratio of centripetal acceleration and acceleration due to gravity is 6.38.
