A balloon of mass m descending with an acceleration a. What mass be dropped from the balloon so that it may go up with the same acceleration a?

A balloon of mass m descending with an acceleration a. What mass be dropped from the balloon so that it may go up with the same acceleration so that it

A balloon is rising upwards with an acceleration. A stone is dropped frome the balloon, is at a height of 50.4 m. The stone reaches the ground after 6s. What was the velocity of the balloon when the stone was dropped?

Mass of a balloon with its contents is 1.5kg. It is descending with an acceleration equal to half of acceleration due to gravity. If it is to go up with the same acceleration keeping the volume same, what amount of mass (in kg) should be decreased?

A balloon with mass m is decending down with an acceleration a (where a lt g ) . How much mass should be removed from it so that it strts moving up with an acceleration a?

A balloon of mass M, carrying some is descending with an acceleration a. When (1)/(4) th of the sand is emptied out the balloon, the balloon descends with a unifrom velocity. Find the initial mass of sand in the balloon.

A balloon is rising upwards from rest with acceleration (g)/(8) . A stone is dropped from the balloon when it is at height H. Show that the time by which the stone will touch the ground is 2 sqrt((H)/(g)) .

A lift of mass 200 kg is moving up with an acceleration of 4 m cdot s^(-2) . What is the tension in the lift cable? If the lift moves down with the same acceleration, what will be the tension in that case? [ g = 9.8 m cdot s^(-2) ]

A balloon at rest on the ground is rising upward with acceleration (g)/(8) . A stone is dropped from the balloon when it is at height H. Show that the time taken by the stone to touch the ground is 1/2 sqrt((H)/(g)) .
