An aeroplane is flying with the velocity of `V_(1)=800kmph` relative to the air towards south.A wind with velocity of `V_(2)=15ms^(-1)` is blowing from west to east.What is the velocity of the aeroplane with respect of the earth.

A

`221.7ms^(-1)`

B

`150ms^(-1)`

C

`82ms^(-1)`

D

`40ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`vecv_(AW)=vecv_(1)=800xx5/18hatj`
`vecv_(W)=vecv_(2)=15hati,vecv_(W)=vecv_(AW)+vecv_(W)`
