A projectile of mass 9.6 kg is launched from the ground with an initial velocity of 12.4 m/s at an angle of 54 degrees above the horizontal (see figure). At some time after its launch, an explosion splits the projectile into two pieces. One piece, of mass 6.5 kg, is observed at 1.42 seconds after the launch to be at a height of 5.9 m and at a horizontal distance of 13.6 m from the launch point. Find the location of the second fragment at that same instant of time.
