Pls Help I Am Really Struggling At This It Is A Vector Question class=

Answer :

Answer:

Step-by-step explanation:

PQ = q-p

PQ = q-p, therefore PS = (2/3)(q-p)

OS = p + (2/3)(q-p) = (2q+p)/3

OR = q + p/2

To make new vectors, chain vectors, follow arrow directions.  

The sum is the line joining the beginning and end points.

If you need to reverse the direction of a vector, simply put a negative sign.
