Answer #1

Here we apply concept of kinematics and parabolic motion. We apply equation of motion for constant acceleration along horizontal and vertical separately.

Launching epeed, y = 12-km/ecc = 12;000 ms 0 - 436_abore horizontal - Along a-ame Lu x _ initial velocity - Yox = V. Caso accht=1670.2 sec so projectile will be on ground after 16 70-2 sec . - 2 tape after or 1 year later it will be on ground at dist
