Question

a packet dropped from a helicopter hovering a a height h from the ground level, reaches the fround in 12 seconds. calculate the value of the height

Answer 1

The packet will freely fall, therefore it's acceleration will be under gravity.

i.e., a=g=9.8m/s²

a = v/t

a = (h/t)(1/t)

9.8 = (h/12)(1/12)

9.8 = h/144

h = 1411.8m
