The area is the length times the height so A= bh ...?
Except when necessary for takeoff and landing, <span>the minimum safe altitude required for a pilot to operate an aircraft over other than congested area is an altitude of 1000 ft above the highest obstacle within a 2000 ft horizontal radius of the aircraft.
It is also good to know that apart from taking off and landing, the aircraft must not operate at a distance less than 500 ft from any person, vessel, structure or vehicle.</span>

Answer:
endothermic
Explanation:
An endothermic is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
Explanation:
The final velocity of the bale have vertical and horizontal components. So, we have:
According to conservation of energy:
Since the plane is flying due east, we have 
. Replacing in (1):
Now, we calculate the momentum of the bale:
From pythagoras theorem we know that:
