and also questions:
1. why does the first hill have to be the highest?
2. why can't the next hill of the roller coaster be as high as the first?
3. what forces slows it down?
4. the kinetic energy is change to what kind of energy by this force?
5. what is the approximate percentage of gpe/ke at different points on your roller coaster labeled a, b,c?

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
