A balloons of mass M is descending at a constant acceleration `alpha`. When a mass m is released from the balloon, it starts rising. With the same acceleration `alpha`. Assuming that its volumes does not change, what is the valule of m?

A balloon of mass m is descending down with an acceleration How much mass should be g/2 removed from it so that it starts moving up with same acceleration?

A balloon with mass m is descending down with an acceleration a (where altg) . How much mass should be removed from it so that it starts moving up with an acceleration a?

A balloon of mass M descends with an acceleration a_(0) . The mass that must be thrown out in order to give the balloon an equal upwards acceleration will be

A balloon of mass 10 kg is raising up with an acceleration of 20 ms^(-2) . If a mass of 4 kg is removed from the balloon its acceleration becomes ( take, g=10ms^(-2) )

A balloon os mass 2 KG is rising up with an acceleration of 4m/s^2 . The upward force acting on the balloon is (g = 10 ms^-2)

A ballon of mass m is rising up with an acceleration a show that the fraction og weight of balloon that must be detached in order to double its acceleration , assuming the upthrust of air to remain the same

A particle of mass m is rigidly attached at A to a ring of mass 3m and radius r . The system is released from rest and rolls without sliding. The angular acceleration of ring just after release is

A balloon is descending with a constant acceleration a, less than the acceleration due to gravity g. The weight of the balloon, with its basket and contents, is w. What weight w, should be released so that the balloon will begin to accelerate upward with constant acceleration a? Neglect air resistance.

A stone is released from a rising balloon accelerating upward with acceleration a. The acceleration of the stone just after the release is

A balloon starts rising from the ground with a constant acceleration of 1.25m//s^(2) . After 8 s, a stone is released from the balloon. Find the time taken by the stone to reach the ground. (Take g=10m//s^(2) )
