A particle is projected with velocity at an angle with the horizontal. At the highest point of its trajectory, it explodes into two fragments of masses and . The lighter fragment falls vertically downwards with zero initial speed. If the range of the original projectile was , the distance from the point of projection where the heavier fragment lands is:
R(1 + m1/(2*m2))
R(1 + 2*m1/m2)
R(1 + m2/(2*m1))
R/2
