0A 30 kg shell in free space explodes into three identical fragments. After the explosion, the fragments rush apart. Forces of mutual interaction between the fragments are long range attractive conservative forces. Immediately after the explosion, velocities of the fragments relative to an inertial frame are 3i+2j m/s, -2i m/s and 5i-5j m/s.
