How much force, in g cm/s2 , is exerted by a golf ball of 50 g striking a tree while accelerating at 20 cm / s2 ? show how you can solve this problem without knowing newton’s second law. explain your solution

Explanation:

Givens

To find the force exerted by the golf ball, we need to use Netwon's second law, which is defined as

In words, when we apply a force to an object with mass , the object will accelerate at .

Now, replacing all given values, we have

Therefore, the force exerted by the golf ball is

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.
