Use the position vs time graph below to answer the following questions. Describe the motion of the object modeled in the graph.

What is the objects velocity?

What is the displacement of the object?

Write the math model that describes the objects motion.

What is the physical meaning of the y-intercept in this situation?

What would be the objects position at t=47 s assuming that the objects motion does not change?

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.
