Ballon is moving with constant acceleration of 1 M per second square a stone is thrown from the ball downward with speed 10m per second with respect to the ballon at the time of projection balloon is at height 120 m from the ground and is moving with speed 20 metre per second time required by the stoneto fall on the ground after the projection will be?
Verified Answer
Ballon is moving with constant acceleration of 1 M per second square a...
Let the velocity with which the stone is thrown be u m/s 
Then its velocity w.r.t to the moving balloon up with 20 m/s will be u + 20. This is given as 10 m/s
So u = -10 m/s
This confirms that the stone is projected upward.
Depth to be traversed  S = 120 m
Acceleration g = -10 m/s^2 as far as projection is concerned
Recalling S = ut + 1/2 g t^2,
-120 = 10t - 5 t^2
Or t^2 -2t - 24 = 0 
(t-6)(t+4) = 0
So t = 6 s
