If a helicopter is moving upwards with acceleration `g` and food packet are thrown from a height `h`. Find time period to reach those packet to ground

A helicopter rises from rest on the ground vertically upwards with a constant acceleration g. A food packet is dropped from the helicopter when is at a height h. The time taken by the packet to reach the ground is close to [ g is the acceeration due to gravity] :

A balloon starts rising upwards with constant acceleration a and afrer time t_(0) , second, a packet is dropped from it which reaches the ground aftre t seconds of dropping . Derermine the value of t .

A balloon starts rising upwards with constant acceleration a and afrer time t_(0) , second, a packet is dropped from it which reaches the ground aftre t seconds of dropping . Derermine the value of t .

A balloon is going upwards with a velocity of 20 m It releases a packet when it is at a height of 160 m from the ground. The time taken by the packet to reach the ground is

A balloon is going upwards with velocity 12 m//sec it releases a packet when it is at a height of 65 m from the ground. How much time the packet will take to reach the ground (g=10 m//sec^(2))
