Acar traveling at a speed of 24 m/s comes to a stop at a red light. how much time will it take for the car to stop if its acceleration is –8.0 m/s2? 3 s

The time it takes for a certain object to stop given its initial velocity is calculated by dividing the velocity by the deceleration given. That is,

                            Time = initial velocity / deceleration

                             Time = (24 m/s) / (8 m/s2)

The equation above will give us an answer of 3 s.

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.
