Given :
Vector A has a magnitude of 63 units and points west, while vector B has the same magnitude and points due south.
To Find :
The magnitude and direction of
a) A + B .
b) A - B.
Solution :
Let , direction in north is given by +j and east is given by +i .
So , 
and 
Now , A + B is given by :
Direction of A+B is 45° north of west .
Also , for A-B :
Direction of A-B is 45° south of west .
( When two vector of same magnitude which are perpendicular to each other are added or subtracted the resultant is always 45° from each of them)
Hence , this is the required solution .
Answer:
13 blocks
Explanation:
The total distance the student travels is 13 blocks.
Distance is the length of path covered during the motion of a body.
To find distance:
Total distance = Number of blocks to the west + number of blocks to the north + number of blocks to the east
Total distance = 3blocks + 4blocks + 6blocks = 13blocks
