JEE PYQ: Motion In One Dimension Question 18
Question 18 - 2020 (05 Sep Shift 1)
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 $[g$ is the acceleration due to gravity$]$:
(1) $t = \frac{2}{3}\sqrt{\frac{h}{g}}$
(2) $t = 1.8\sqrt{\frac{h}{g}}$
(3) $t = 3.4\sqrt{\frac{h}{g}}$
(4) $t = \sqrt{\frac{2h}{3g}}$
