Yes. I am familiar till the part that the maximum angular frequency is 8 rad/s. So using the Nyquist rate, the sampling frequency should be twice the max frequency. But I don't understand how to systematically approach this kind of question. Thank you.
My attempt:
At node 1 > 4 = 6 + I1
Node 2 > I1 + I2 = I 2
Node 3 > 6 = I 3 + I 4
I1 = (V1 - 4)/21
In node 1,
Using the equation for I1, V1 = -38V.
I2 = (V1 - 4 - 1)/2
So, I2 = -21.5APower supplied by the 1V battery is
P=VI
P=-21.5 x 1
P=-21.5W
I am not sure of my method, I just started...
Is there like a rule of thumb, or a simple hack for assigning current direction in circuit analysis? Even when I m consistent with the direction I choose, I still get the wrong answer most of the time.
Like
1. Do current source or voltage source affect when choosing current direction?

[ A train starting from rest accelerate at the rate of 6m/s² for 20 seconds to attain a constant speed and it traveled for another 20 seconds and decelerate at the rate of 3m/s² for 20 seconds. Calculate the total distance (in kilometer) traveled by the train.
That's the question. I found it...
