Answer:
a)
Now we can replace the velocity for t=1.75 s
For t = 3.0 s we have:
b)
And we can find the positions for the two times required like this:
And now we can replace and we got:
Explanation:
The particle position is given by:
Part a
In order to find the velocity we need to take the first derivate for the position function like this:
Now we can replace the velocity for t=1.75 s
For t = 3.0 s we have:
Part b
For this case we can find the average velocity with the following formula:
And we can find the positions for the two times required like this:
And now we can replace and we got:
Answer:
a
b
Explanation:
From the question we are told that
The number of identical drippers is n = 60
The diameter of each hole in each dripper is
The diameter of the main pipe is
The speed at which the water is flowing is
Generally the amount of water used in one hour = 3600 seconds is mathematically represented as
Here A is the area of the main pipe with value
=>
=>
So
=>
=>
Generally the area of the drippers is mathematically represented as
=>
=>
Generally from continuity equation we have that
=>
=>
