Two cars approach an extremely icy four-way perpendicular intersection. car a travels northward at 26 m/s and car b is traveling eastward. they collide and stick together, traveling at 12o north of east. what was the initial velocity of car b? you may assume that the cars have the same mass. round your answer to one decimal place.

Explanation:

As we know that momentum conservation is hold good when we consider elastic or inelastic collision between two objects

so here we have

so here we have

so we have

since we know that final velocity of two cars at 12 degree angle in North of East

so we will have

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.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
