Calculate the resultant of the pair of velocities 100km/h north and 75 km/h south. Calculate the resultant if both of the velocities are directed north.
How do you do that
You add vectors. If both are N, then 175km/n is the resultant. If one is S, it is the same as adding a negative N, so add 100km/h N + -75km/hr N
