When you combine 2 velocities that are in the same directions, add them together to find the resultant velocity. When you combine 2 velocities that are in opposite directions, subtract the smaller velocity from the larger velocity to find the resultant velocity.

As the velocities are in the same direction then addition of vectors becomes so easy. We simply add the magnitudes of the velocities. If velocities go exactly opposite, then we get the difference of their magnitudes. If velocity vectors get inclined, then we use the parallelogram law of vectors to get the resultant.

That sounds like a rocket.

Equilibrant vector is the opposite of resultant vector, they act in opposite directions to balance each other.

The zero-vector has no direction.

Because the two velocities are in the opposite directions, you can directly subtract their numeric values. (1400 - 20) kph in the larger velocities direction. The answer is 1380 kph West.

First you have to resolve all forces into vertical and horizontal. If it on a slope take the reaction force as vertical and the slope as horizontal. Then equate the opposite forces, for example the friction and the driving force, and use maths to figure out the resultant.
