** 55 POINTS, I WILL MARK BRAINLIEST A student placed a small, self powered car on the ground and released it from rest. Times were recorded at 1m, 2m and 3m from the start as follows:

1m 1.16 s

2m 1.89 s

3m 2.45 s

The car's acceleration between the two meter mark and the three meter mark was m/s^2.

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.
