A hot air balloon is traveling vertically upward at a constant speed of 3.1 m/s?

A hot air balloon is traveling vertically upward at a constant speed of 3.1 m/s. When it is 11 m above the ground, a package is released from the balloon. After it is released, for how long is the package in the air? The acceleration of gravity is 9.8 m/s^2 .

ground?
Answer in units of m/s.

-Now assume the hot air balloon is traveling
vertically downward at a constant speed of
3.1 m/s.
After the package is released, how long is it
in the air?
Answer in units of s.
-What is its speed just before impact with the
ground?
Answer in units of m/s.
