When a body gets separated from another moving body, it acquires the velocity of the moving body. So, when a portion of meteor gets separated, it acquires the velocity of meteor, i.e. 50 kmh -1.

Q. A portion of a meteor moving at a constant rate of $50 km h^{- 1}$ gets separated from its surface, when it enter earth's atmosphere. Find the velocity of the portion of meteor at the instant after it gets separated.

$100 km h^{- 1}$

$50 km h^{- 1}$

$0 km h^{- 1}$

$200 km h^{- 1}$

When a body gets separated from another moving body, it acquires the velocity of the moving body.
So, when a portion of meteor gets separated, it acquires the velocity of meteor, i.e. $50 km h^{- 1}$ .

Q. A portion of a meteor moving at a constant rate of 50kmh−1 gets separated from its surface, when it enter earth's atmosphere. Find the velocity of the portion of meteor at the instant after it gets separated.

100kmh−1

50kmh−1

0kmh−1

200kmh−1
