A jet airplane travelling at the speed of `500 km h^(-1)` ejects its products of combustion at the speed of `1500 km h^(-1)` relative to the jet plane. The speed of the products of combustion with respect to an observer on the ground is

`1000 kmh^(-1)` in the direction west to east

`1000 kmh^(-1)` in the direction east to west

`2000 kmh^(-1)` in the direction west to east

`2000 kmh^(-1)` in the direction east to west

Text Solution

Verified by Experts

The correct Answer is:

`vec(V)_(A)=-500 hati rArr vec(V)_(GA)+vec(V)_(A)=V_(GAS)`
`vec(GA)=1500 hatirArr 1500 hati-500 hati=1000 hati`
