An object of mass \( 10 \mathrm{~kg} \) is launched from the ground at \( t=0 \), at an angle of \( 37^{\circ} \) above the horizontal with a speed of \( 30 \mathrm{~m} / \mathrm{s} \). At some time after its
launch, an explosion splits the
projectile into two pieces. One
piece of mass \( 4 \mathrm{~kg} \) is observed at
\( (105 \mathrm{~m}, 43 \mathrm{~m}) \) at \( t=2 \mathrm{~s} \). Find the
location of second piece at \( t=2 \mathrm{~s} \).
(1) \( (10,2) \)
(2) \( (48,16) \)
(3) \( (10,-2) \)
(4) Information insufficient
