Question

Two airplanes are flying in the same direction (one is just above the
other). The airplane at higher altitude has a velocity of 150 m/s and the
lower one has 155 m/s. The upper plane started bombing downward. The
bombs were being dropped so that it fell vertically on the plane below.
The bomb made holes wherever it fell. If the upper plane drops 10 bombs
per minute, then what is the distance between two holes along the lower
plane?

Answer 1

Explanation:

we know that,

h=2ut+1/2gt

u=0 h=980m

t=2gh=9.8×2×980

t=14.14sec
