Question

A bomb explodes in mid air in two equal fragments what is the relation between the direction and motion of the two fragments

Answer 1

Answer:

they will fly into the opposite direction of each other

Answer 2

Let the bomb have a mass 2m,

Let the mass and velocity of the first fragment be m and v1 and of the 2nd be m and v2 respectively.

The initial velocity of the bomb be 0 assuming the bomb is at rest in air when it exploding

Intial momentum = final momentum

2m(0) = mv1 + mv2

=> mv1 + mv2 = 0

=> v1 = -v2

This means the two fragments will have equal but opposite velocities.

Thus direction of fragments opposite of each other.
