An aeroplane is moving with a velocity u. It drops a packet from a height h. The time t taken by the packet in reaching the ground will be

An aeroplane is moving with horizontal velocity u at height h . The velocity of a packet dropped from it on the earth's surface will be ( g is acceleration due to gravity)

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 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 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 ascending at the constant rate of 9.8 m//sec at a height of 98 m above the ground a packet is dropped from it. If time taken by the packet to reach the ground is (1 + sqrt(3lambda))sec . Find lambda . (Use g = 9.8 m//s^(2) )

A balloon is ascending at the constant rate of 9.8 m//sec at a height of 98 m above the ground a packet is dropped from it. If time taken by the packet to reach the ground is (1 + sqrt(3lambda))sec . Find lambda . (Use g = 9.8 m//s^(2) )

A stone is dropped from height h. Arrive at an expression for the time taken to reach the ground.

A packet is dropped from a balloon that is moving upward when the balloon is at a height 60 m above ground. If the speed of the balloon at the moment of release of packet is 5 m/s, time taken by the packet to reach ground will be: (Take g = 10 m//s^(2) )

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
