Question

An aircraft executes a horizontal loop of radius 1 km with a speed of 900 km/h

Answer 1

Answer:

Explanation:

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
