A projectile of mass 9.6 kg is shot off from the gound with an initial velocity of 12.4 m/s

A projectile of mass 9.6 kg is shot off from the gound with an initial velocity of 12.4 m/s at an angle 54 degrees above the horizontal.a) Where does the projectile hit the ground again (the terrain is completely horizontal for this trajectory) and how long after the launch.Suppose that instead, and at some time after its launch, an explosion splits the projectile into two pieces. One piece, of mass 6.5kg, is observed at 1.42 s after the launch at a height of 5.9 m and a horizontal distance of 13.6 m from the launch point.b) Find the location of the second fragment (essentially the rest of the mass at that same time.(Did it hit the ground?)
