You have three independent equations so can solve for the three unknowns, which are Io, I1, and Vo. Enter these equations into your calculator (and recall that you might need to place them in standard form first) and solve. Since your equations will contain complex numbers, they must be entered carefully to avoid errors. Give the values for the three unknown phasors that result from solving the three equations, and include the correct units.

The values are:

Explanation:

the attached figure shows the diagram. The equation is the following:

(eq. 1)

Voltage across the 40 Ω is equal:

(eq. 2)

Applying the Kirchhoff´s voltage law:

(eq. 3)

Equation 1 and 2:

(eq. 4)

Substituting in eq. 3

Substituting in eq. 4

Substituting in eq. 2:

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
