PLEASE HELP WITH THOSE TWO QUESTIONS. 1) A 855 kg car pushes on the road with 5450 N of force. What is the magnitude of the force the road exerts back on the car, and what is the acceleration of the car?

2) A 68.0 kg baseball player throws a 145 g baseball directly east. He throws the baseball with a force of 4.40 N. What is the resulting acceleration of the player?

Explanation:

Mass, m = 855 kg

Force, f = 5450 N

force exerted by th road on the  car = force exerted by the car on the road = 5450 N (  Newton's third law of motion )

acceleration, a = f / m

= 5450 / 855

= 6.37 m/s^2

Hope this helps

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.
