Question

When a bomb explodes in mid-air , its

• A. momentum increases
• B. Momentum remains constant
• C. Kinetic energy increases
• D. Kinetic energy remains constant

Answer 1

Answer: (B), (C)

Kinetic energy increases

Correct answer is (B) and (C):

Explanation:

1. The momentum of the fragments remain conserved whereas during the explosion because no external force is applied.
2. chemical energy would be released which gets converted into Kinetic energy
   Thus kinetic energy alone increases

Hence option (b) and (c) is the correct answer.
