The Concorde jet was a supersonic plane created in 1976 to speed
transportation across the ocean. It traveled at twice the speed of sound,
shortening a normal seven- to eight-hour transatlantic trip to three and a half
hours. However, the Concorde still had to fly in the same atmospheric conditions
as every other plane. Given this information, answer the following questions (15
points)

A. In which layer of the atmosphere did the Concorde cruise? (5 points)
B. What are the characteristics of this layer that make it the ideal layer for the
Concorde to travel? (5 points)
C. Why wouldn't it travel higher? (3 points)
D. Why wouldn't it travel lower? (2 points)

answer: option c.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
