1. The problem statement, all variables and given/known data A Hot air balloon is traveling vertically up- ward at a constant speed of 2.6 m/s. When it is 19 m above the ground, a package is released from the balloon. The acceleration of gravity is 9.8 m/s^2. After it is released, for how long is the package in the air? Answer in units of s. 2. Relevant equations 3. The attempt at a solution I tried doing X = .5at^2 + vit and using -2.6, but it didnt work.
