An object moves along the x axis according to the equation x(t) 3.00t^2 -2.00t 3.00. what is the instantaneous acceleration?

6 m/s^2

Explanation:

The object moves along

The time rate of change of displacement gives the instantaneous velocity.

It means the differentiation of displacement function with respect to time gives the value of instantaneous velocity.

So, differentiate position function with respect to time, we get

v = 6t - 2

Now we know that time rate of change of velocity gives instantaneous acceleration.

It means the differentiation of velocity function with respect to time gives the value of instantaneous acceleration.

So, differentiate velocity function with respect to time, we get

a = 6 m/s^2

Thus, the instantaneous acceleration of the object is 6 m/s^2.  

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.

dang that balls went far
