Vector A has magnitude 2 units and is directed to the north. Vector B has magnitude 5 units and is directed to the south. Calculate the magnitude and direction of A+B

Vector A+B has a magnitude of 3 units and is directed to south

Explanation:

Vector A is a vector in the positive direction  (north)with a magnitude of 2 .  

Vector B is a vector in the negative direction (south) with a magnitude of 5.

Magnitude of A+B=2+(-5)  = -3

Direction is south.

Vector A+B has a magnitude of 3 units and is directed to south
