Question

A portion of a meteor moving at a constant rate of $50\, kmh ^{-1}$ 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.

• A. $100\, kmh ^{-1}$
• B. $50\, kmh ^{-1}$
• C. $0\, kmh ^{-1}$
• D. $200\, kmh ^{-1}$

Answer 1

Answer: (B)

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. $50\, kmh ^{-1}$.
