An object with mass 60 kg moved in outer space. when it was at location < 13, -19, -3 > its speed was 3.5 m/s. a single constant force < 220, 320, -120 > n acted on the object while the object moved from location < 13, -19, -3 > m to location < 18, -11, -8 > m. then a different single constant force < 150, 230, 220 > n acted on the object while the object moved from location < 18, -11, -8 > m to location < 22, -17, -3 > m. what is the speed of the object at this final location?
final speed = m/s

a person with a mass of 106kg has a weight of 1060n

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.
