If bomb at rest explodes into fragments the two fragments travel in opposite direction explain​

Answer»

Answer:

bomb at rest EXPLODES into TWO pieces. Let the mass of bomb be M and mass of two pieces be m

1

and m

2

respectively. Now, according to conservation of MOMENTUM:

Mv=m

1

v

1

+M

2

v

2

Here v=0 (bomb is at rest) and v

1

and v

2

are velocities of two masses after explosion.

M(0)=m

1

v

1

+m

2

v

2

m

1

v

1

+m

2

v

2

=0

m

1

v

1

=−m

2

v

2

Now, masses cannot be NEGATIVE that means the sign BELONGS to velocities. Therefore, the two pieces travel in opposite direction.
