Correct Question:-
- A bomb of mass 50 kg at rest explodes into two pieces of masses 40 kg and 10 kg . The velocity of bigger piece is zero then Find velocity of smaller piece .
AnswEr :-
Explanation:-
Given :-
- A bomb of mass 50 kg at rest explodes into two pieces of masses 40 kg and 10 kg .
- The velocity of bigger piece or velocity of 40 kg exploded bomb is zero m/s
To Find :-
- The velocity of smaller piece or velocity of 10 kg exploded bomb .
Solution:-
- ☆ According to Conservation law of momentum.
Or ,
Here ,
- ( Mass )¹ -: The mass of bigger piece in which bomb is exploded or m¹ = 40 kg .
- ( Velocity)¹ -: The velocity bigger piece in which bomb is exploded or v¹ = 0 m/s .
- ( Mass )² -: The mass of smaller piece in which bomb is exploded or m² = 40 kg .
- ( Velocity)² -: The velocity bigger piece in which bomb is exploded or v² = ?
Now ,
Therefore,
Hence ,
