Acar traveling 31 mi/h accelerates uniformly
for 6 s, covering 401 ft in this time.
what was its acceleration? round your
answer to the nearest 100th place.
answer in units of ft/s? .

Explanation:

For this exercise we need to use th following formula:

Where is the distance, is the initial velocity, is the acceleration and is the time.

The first step is to convert from to . Since:

We get:

Knowing that:

We can substitute values into the formula and solve for "a":

Rounded to the nearest 100th place:

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.

the answer to this is proletariats.

hope this : )
