come and find me i gave you all the information you basically needed to find me
and you can only come to my school on monday Tuesday Wednesday Thursday and f riday
some days i might be absent
or either you can call me school to find me
To find the resultant velocity when combining two velocities going in opposite directions, you simply subtract the smaller velocity from the larger velocity. The direction of the resultant velocity will be in the direction of the larger velocity.
When two velocities are in opposite directions, subtract the smaller velocity from the larger one. The direction of the resulting velocity will be in the direction of the larger velocity. This is because the smaller velocity is effectively being subtracted from the larger one.
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.
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.
Only if the two velocities are equal in magnitude but in opposite directions.
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.

When combining velocities in the same direction, you simply add them together. For velocities in opposite directions, you subtract them. The resulting velocity will depend on the direction and magnitudes of the individual velocities being combined.
The resultant velocity is found by subtracting the smaller velocity from the larger one if they are in opposite directions. This is because the velocities are working against each other to some degree, resulting in a net velocity that is the difference between the two.
When two vectors are in opposite directions, their resultant is the difference between their magnitudes, with the direction of the larger vector. This means the resultant vector points in the direction of the larger vector and its magnitude is the difference between the magnitudes of the two vectors.
