To the captain of a ship A travelling with velocity `vecv_(A)=(3hati-4hatj)km..h`, a second ship B appears to have a velocity `(5hati+12hatj) km//h`. What is the true velocity of the ship B?

A

`2hati+16hatjkm//h`

B

`13hati+8hatjkm//h`

C

`-2hati-16hatjkm//h`

D

`8(hati+hatj) km//h`

Text Solution

Verified by Experts

The correct Answer is:
d
`vecv_(B)=vecv_(BA)+vecv_(A)`
`=(5hati+12hatj)+(3hati-4hatj)`
`v_(B)=8hati+8hatj`
