A helicopter rises from rest on the ground vertically upwards with a constant acceleration \( g \). A food packet is dropped from the helicopter when it is at a height \( h \). The time taken by the packet to reach the ground is close to [ \( \mathrm{g} \) is the acceleration due to gravity]https://bit.ly/YTAI_PWAP https://www.pw.live
