When a professional football player kicks the football, their foot is in contact with the ball for 33 milliseconds. The ball, originally at rest, now flies away at a speed of 31 meters per second. If the mass of the ball is 417 grams, then calculate the average force between the ball and their foot, in Newtons.

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.
