Question
A projectile of mass m is fired with a velocity v0 at an angle θ with the horizontal. At the highest position in its flight, it explodes into two fragments of masses m1=m3 and m2=2m3. The fragment of mass m1 falls vertically with zero initial speed.
(a) Find the initial velocity of the fragment m2.
(b) Find the distance d at which the fragment m2 will land with respect to m1.
