A plane flying horizontally at 100 m/s at a height of 1000 m releases a bomb from it. Find the time it takes to reach the ground.Â

We have,Â

Initial distance, yo = 0

Height attained after time t, y = 1000 mÂ

Initial velocity, uy = 0 m/sÂ

Acceleration, ay = 9.8 m/s2Â

Time = tÂ

Now, using the equation of motion, we haveÂ

Therefore, 14.28 sec ia taken for the bomb to reach the ground.Â
