A shell has negligible velocity exploded in air into four equal pieces

A shell has negligible velocity exploded in air into four equal pieces A, B, C & D. Velocities of pieces A, B, C are 20m/s , 20m/sjand 10 m/sk respectively. Where Z axis is vertically upwards then 2 sec after the explosion (A) Separation between the pieces A & D will be 40/3 m (B) Separation between the pieces B & D will be 40/2 m (C) Separation between the pieces C & D will be 40/3 m (D) Separation between the pieces A & B will be40/3 m
