Arock is thrown downward from a height of 207 m with an initial velocity of 5.37 m/s. approximately how fast will it it be moving 3.03 seconds after it was thrown? (assume no air resistance.)

List the known information:

Use the kinematic equation .

Plug in the given values:

This would be 35.064 m/s downward, or 35 m/s downward with significant figures taken into account.

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.
