Q3. A 4-kg projectile travels with the horizontal v velocity of 610 m/s before it explodes and breaks into two fragments A and B of mass 1.50 kg and 2.50 kg, respectively. If the fragments travel along the parabolic trajectories shown, conclude the magnitude of velocity of each fragment just after explosion and horizontal distance dA where segment A strikes the ground at C.
