Identical packets are dropped from two areoplanes, one above the equator and the other above the north poole, both at height h. Assuming all condition are identical, will those packets take same time to reach the surface of earth. Justify your answer.

Assuming earth to be spherical, at what height above the north pole, value of g is same as that on earth's surface at equator?

Assertion: A balloon ascends from the surface of earth with constant speed. When it was at a height 50 m above the ground, a packet is dropped from it. To an observer on the balloon, the displacement of the packet, from the moment it is dropped to the moment it reaches the surface of earth, is 50 m Reason: Displacement (vector) depends upon the reference frame used to measure it.

(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 food packet is dropped from an aeroplane, moving with a speed of 360 kmph in a horizontal direction, from a height of 500m. Find (i) its time of decent (ii) the horizontal distance between the point at which the food packet reaches the ground and the point above which it was dropped.

Two balls are dropped from heights h and 2h respectively from the earth surface. The ratio of time of these balls to reach the earth is.
