A 16.0 kg canoe moving to the left at 12.0 m/s makes an elastic head-on collision with a 4.00 kg raft moving to the right at 6.00 m/s. After the collision, the raft moves to the left at 22.7 m/s. Disregard any effects of the
water. Find the velocity of the canoe after the collision.

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.
