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

Be at rest

Move with different velocities in different directions

Move with the same velocity in opposite directions

Move with the same velocity in same direction

Solution

(c)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.
