A man in a balloon throws a stone downwards with a speed of `5 m//s` with respect to balloon. The balloon is moving upwards with a constant acceleration of `5 m//s^2`. Then velocity of the stone relative to the man after `2` seconds is.

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

A body, thrown from the balloon reached the ground in 30 seconds. If the balloon is moving upwards with constant velocity of 100 m//s , then find the height of the balloon at that time.

A packet is dropped from a balloon which is going upwards with the velocity 12m//s . The velocity of the packet after 2 seconds will be

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 balloon starts rising from the ground with an acceleration of 1.25m//s^2 . After 8s stone is released from the ballon. What distance the stone will cover?

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

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

A a certain instant of time a ballon is moving downwards with speed of 5m/s. It has a constant retardation of 5m/s2. A man in the ballon drops a stone at that instant. It hits the ground after 2s. Then the speed with which the stone hits the ground is.
