A balloon is ascending at the rate of 20 m/sec. When it is at a height 100 m from ground, a packet is dropped from the balloon.

What will be the velocity of the packet w.r.t.

(i) ground

(ii) balloon, when it was just dropped?

Solution

Speed at which the balloon is ascending, v = 20 m/s
Height of balloon from the ground = 100 m
With respect to ground, the velocity of the packet will be 20 m/sec upward.
With respect to balloon, its velocity will be zero.
