Discuss the explosion of a projectile.
(N/A) As shown in the figure,a projectile following a parabolic path explodes into fragments midway in the air.
The forces leading to the explosion are internal forces,and they contribute nothing to the motion of the centre of mass.
Total external force,which is the force of gravity acting on the body,remains the same before and after the explosion.
Therefore,the centre of mass continues to move under the influence of the external force along the same parabolic trajectory as it would have followed if there were no explosion.

An impulse gives a velocity of $7 \,m/s$ to the heavier block in the direction of the lighter block. The velocity of the centre of mass is ....... $m/s$.
