A lift accelerates downwards from rest at rate of `2 m//s^(2)`, starting `100 m` above the ground. After 3 sec, an object falls out of the lift. Which will reach the ground first? What is the time interval between their striking the ground?

If from point 100 m above the ground the angles of depression of two objects due south on the ground are 60^(@) and 45^(@) , then the distance between the objects is :

A balloonist release a ballast bag from a balloon rising at 40 ms at a time when the balloon is 100 m above the ground. If g = 10m/s2 then the bag reaches the ground in:

A plane flying horizontally at 100 m s^-1 releases an object which reaches the ground in 10 s . At what angle with horizontal it hits the ground ?

A plane flying horizontally at 100 m s^-1 releases an object which reaches the ground in 10 s . At what angle with horizontal it hits the ground ?

A ballon starts rising from ground from rest at some constant acceleration. After some time, a storne is dropped from it. If the stone reaches the ground in the same time in which balloon reached the dropping poing from ground, find the acceleration of the balloon.

A lift, initially at rest on the ground, starts ascending with constant acceleration 8m//s^(2) After 0.5 seconds, a bolt falls off the floor of the lift. The velocity of the lift at the instant the bolt hits the ground is m/s .[Take g=10 m//s^(2) ]

A balloon starts rising from ground from rest with an upward acceleration 2m//s^(2) . Just after 1 s, a stone is dropped from it. The time taken by stone to strike the ground is nearly
