A helicopter is ascending vertically with a speed of 8.0 "ms"^(-1) . At a height of 12 m above the earth, a package is dropped from a window. How much time does it take for the package to reach the ground ?

(A): A balloon ascends from the surface of earth with constant speed. When it was at a height 50m above the ground, a packet is dropped from it. To an abserver on the balloon, the displacement of the packet, from the moment it is dropped to the moment it reaches the surface of earth is 50m. (R): Displacement vector does not depend upon the reference frame used to measure it.

A balloon rises with uniform velocity of 10 ms^(-1) . When the balloon is at a height of 75 m if a stone is dropped from it the time taken by it to reach the ground is
