1. The problem statement, all variables and given/known data A 4-kg projectile travels with a horizontal velocity of 600 m/s before it explodes and breaks into two fragments A and B of mass 1.5 kg and 2.5 kg, respectively. If the fragments travel along the parabolic trajectories shown, determine the magnitude of velocity of each fragment just after the explosion and the horizontal distance dA where segment A strikes the ground at C. 2. Relevant equations mAVA1x + mBVB1x = mAVA2x + mBVB2x 3. The attempt at a solution (1.5 kg)(600 m/s) + (2.5 kg)(600 m/s) = (1.5 kg) VA2cos(45) + (2.5 kg) VB2cos(30) 2400 kg m/s = (1.5cos(45) kg) VA2 + (2.5cos(30) kg) VB2 Solving two unknowns?
