I am rising upward in a hot air balloon. I am holding my coffee container and i accidentally let go of it when I am leaning out and enjoying the view. At the instant I let go of the container, the balloon is rising at 12 m/s and the container is exactly 15 m above the ground.
A) With what speed does my coffee container strike the ground?
B) For how many seconds has it been in the air since i released it until it strikes the ground?
C) Whats the greatst height the container achieved in its flight?
