An aeroplane is flying with a uniform speed of `150 km h^(-1)` along the circumference of a circle. The change in its velocity in half the revoution (in km `h^(-1)`) is

A

150

B

100

C

200

D

300

Text Solution

Verified by Experts

The correct Answer is:
D
The range in velocity in half revolution,
`Delta v = 150 - (-150)`
`= 150 + 150`
`= 300 km h^(-1)`
