A 4-kg projectile travels with a horizontal velocity of 600 m/s before it explodes and breaks into two fragmentsAandBof 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 d_{A}where segmentAstrikes the ground atC.

2. Relevant equations

m_{A}V_{A1x}+ m_{B}V_{B1x}= m_{A}V_{A2x}+ m_{B}V_{B2x}

3. The attempt at a solution

(1.5 kg)(600 m/s) + (2.5 kg)(600 m/s) = (1.5 kg) V_{A2}cos(45) + (2.5 kg) V_{B2}cos(30)

2400 kg m/s = (1.5cos(45) kg) V_{A2}+ (2.5cos(30) kg) V_{B2}

Solving two unknowns?
