A balloon starting from rest ascends vertically with uniform acceleration to a height of 100m is 10s. The force on the bottom of the balloon by a mass of 50 kg us (`g=ms^(-2)`)

A balloon starting from rest moves vertically upwards with an acceleration (g/8) ms^(-1) .If a stone falls from it after 8 seconds from the start,find time taken by the stone to reach the ground.

A balloon starts from rest from the ground and moves with uniform acceleration g/8. When it reaches a height h a ball is dropped from it. Find the time taken by the ball to reach the ground.

A balloon starts from rest from the ground and moves with uniform acceleration g/8.When it reaches a height h a ball is dropped from.It find the time taken by the ball to reach the ground.

A balloon starts from rest from the ground and moves with uniform acceleration g/8. When it reaches a height h a ball is dropped from it. Find the time taken by the ball to reach the ground.

A balloon starts from rest, moves vertically upwards with an acceleration g/8 "ms"^(-2) . A stone falls from the balloon after 8s from the start. Find the time taken by the stone to reach the ground (g=9.8 ms^(-2))

A bolloon starts from rest moves vertically upwards with an acceleration g//8 ms^(-2) a stone falls from the balloon after 8 s from the start. Further time taken by the stone to reachg the ground (g=9.8ms^(-2)) is
