A3 kg block is sliding across a horizontal surface. the initial speed of the block is 4 m/s, but because of friction the block’s speed will decrease at a constant rate (i. e., constant acceleration) until the block finally comes to a stop after sliding 8 m. what is the magnitude of the acceleration of the block (in m/s^2)? what is the average power (in w) supplied by friction as the block slows to a stop?

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

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.

does anyone know or what?
