The acceleration will remain the same (assuming air resistance is negligible or consistent) however the velocity will change in magnitude.
Answer:
The rate at which velocity changes with respect to a change in time is called. acceleration.
Explanation:
<span>B. Controls: The known powders attributes are already studied, so the are used as control measures to compare with the findings in the experiment with the unknown powders.</span>
Answer: Negative acceleration
Explanation:
According to the described situation we have two velocities:
-An initial velocity during the first hour:
-A final velocity during the last 200 miles:
As we can see, the final velocity is less than the initial velocity, this means the plane's velocity decreased.
On the other hand, acceleration is defined as <u>the variation of velocity in time:</u>
Since the plane's velocity decreases, the acceleration is negative.
Hence, this situation is an example of negative acceleration.
