write my assignment 751

A hot air balloon is traveling vertically upward at a constant speed of 3.8 m/s. When it is 13 m above the ground, a package is released from the balloon. The acceleration of gravity is 9.8 m/s. 1. After it is released, for how long is the package in the air?  Answer in units of s.2. What is its speed just before impact with the ground? Answer in units of m/s

Now assume the hot air balloon is traveling vertically downward at a constant speed of 3.8 m/s.

3. After the package is released, how long is it in the air? Answer in units of s.

4. What is its speed just before impact with the ground? Answer in units of m/s
