A cannon shell is fired to hit a target at a horizontal distance d. However , it breaks into two parts of mass ratio 1:2 at its height point. The smaller part returns to cannon. The other part (i) will fall at a distance d/2 beyond the target (ii) have eight times the kinetic energy of smaller part (iii) the increase in kinetic energy of system after explosion is 200% (iv) after explosion , heavier part will take more time as compared to smaller part , to strike the ground
