What is approximately the centripetal acceleration (in units of acceleration due to gravity on earth, g = 10 m `s^(-2)`) of an air-craft flying at a speed of 400 m `s^(-1)` through a circular arc of radius 0.6 km ?

A

26.7

B

16.9

C

13.5

D

30.2

Text Solution

Verified by Experts

The correct Answer is:
A
Here, `v=400ms^(-1),r=0.6xx10^(3)m,g=10s^(-2)`
Centripetal acceleration,
`a_(c)=(v^(2))/(r)=((400ms^(-1))^(2))/(0.6xx10^(3)m)=26.7xx10ms^(-2)`
In the units of `g(=10ms^(-2))`, the centripetal acceleration is 26.7
