Question

A shell initially at rest explodes into two pieces of equal mass, then the two pieces will

• A. Be at rest
• B. Move with different velocities in different directions
• C. Move with the same velocity in opposite directions
• D. Move with the same velocity in same direction

Answer 1

The correct option is C

Move with the same velocity in opposite directions

According to law of conservation of linear momentum both pieces should possess equal momentum after explosion. As their masses are equal therefore they will possess equal speed in opposite direction.
