C. The average acceleration is positive and smaller in magnitude than the initial acceleration.
<h3>
What is average velocity?</h3>
Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.
a = Δv/Δt
where;
- Δv is change in velocity
- Δt is change in time
a = (250 - 248) / (70 - 40)
a = 0.067 m/s²
Thus, we can conclude that the average acceleration is positive and smaller in magnitude than the initial acceleration.

Answer:
204kW
Explanation:
P = t x ω = 500 x (2πx3900/60) = 204203W = 204kW
Answer:
Because Physics is mainly composited of math
Explanation:
If you really think about it the only way any science works is off maths, whether that be measuring the amount of NaOH to put into a solution or determening the amount of sugar you want in a cake it all relys on maths
Yes, yea, yep, you don't make much sense.
