A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is 0=2.25 m/s . Knowing that at the time of the release the balloon was 35.8 m above the ground, determine the time it takes for the bag to reach the ground from the moment of its release. Use =9.81 m/s2.
