A vehicle collides with a rain gate barrier when traveling at 27.75m/s and is brought to rest in 0.075s. if the mass of vehicle and the occupant is 1000kg .calculate the average force on the vehicle .the driver used his seat belt which restricted his movement through a distance of 0.25m relative ti the seat. what was the average force exerted by the belt on the driver if the driver's mass is 100kg.​

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.
