Answer:
we approach a maximum or minimum the values of the ordinate are closer and closer and when passing this point the values change their trend
Explanation:
The reason for this process occurs because as we approach a maximum or minimum the values of the ordinate are closer and closer and when passing this point the values change their trend if they were rising, they begin to fall and if they were falling they begin to rise. Therefore the maximum point is a point of inflection of the curve since its trend changes.
Another way of looking at this process is that mathematically the point where there is a maximum or a minimum corresponds to the point where the first derivative is equal to zero, this is the slope of the line is horizontal, so the points before after correspond to values with slope of different sign.
So you problem ask to find or calculate the approximate diameter of the planet Neptune, based on my calculation the diameter of Planet Neptune would be 5972. I hope you are satisfied with my answer and feel free to ask form more.
Answer:
a_x(3.98) = 7.0844 m/s^2
Explanation:
Given:
- The eastward component of car's velocity is given as follows:
v_x (t) = 0.890*t^2
For, 0 s < t < 5 s
Find:
What is the acceleration of the car when v_x = 14.1 m/s ?
Solution:
- We will first compute the time t at which the velocity v_x component equals 14.1 m /s :
14.1 = 0.890*t^2
t = sqrt (15.8427)
t = 3.98 s
- Now use the relation of v_x and derivative to obtain a_x acceleration in eastward direction:
a_x (t) = dv_x / dt
a_x(t) = 1.78*t
- Evaluate at t = 3.98 s:
a_x(3.98) = 1.783.98
a_x(3.98) = 7.0844 m/s^2
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton. meter (N. ... One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m
Answer:
<h3>The answer is 2800 kg</h3>
Explanation:
The mass of the truck can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>2800 kg</h3>
Hope this helps you
