A 60-kg rocket is fired from O with an initial velocity v0 = 125 m/s along the indicated trajectory. The rocket explodes 7 seconds after launch and breaks into three pieces A, B, and C having masses of 10, 30, and 20 kg, respectively. Pieces B and C are recovered at the impact coordinates shown. Instrumentation records reveal that piece B reached a maximum altitude of 1500 m after the explosion and that piece C struck the ground 6 seconds after the explosion. What are the impact coordinates for piece A? Neglect air resistance.
