In the battle for dominance in 1952 Korea, Americans are shooting North and the Vietcong are shooting south. In the heat of warfare, a 0.00402 kg (5.56 round) flying at 948 m/s strikes a 0.00933 kg (7.62 round) at flying south. After they strike one another, without sticking, both bullets fall straight down to the ground. What was the velocity of the (7.62 round)?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

no simpler subs form complex ones. synthesise = make
