Q1. Throughout liftoff a hot air balloon accelerates upward at a rate of 2.7 ms^2. The balloonist drops an object over the side of the gondola when speed is 14 m/s^2.
- What is the magnitude of objects acceleration after it is released (relative to the ground).
- How long does the object take to hit ground?
