Question:

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.

Answer:

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

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

Centripetal acceleration,  ac  =  v2 /  r

= (250)2  / 1000  = 62.5 m/s2

Acceleration due to gravity, g = 9.8 m/s2

ac / g = 62.5 / 9.8 = 6.38

a=  6.38g
