Question

Really confused about b, how to get the position of w. Hope someone could help me.

Answer 1

Answer + Step-by-step explanation:

(a)

`\overrightarrow{PQ} =a+(3)/(5) b`

(b)

we are given:

`\left\vert \overrightarrow{RQ} \right\vert =(3)/(5) \left\vert \overrightarrow{OP} \right\vert`

Then

`\left\vert \overrightarrow{WR} \right\vert =(3)/(5) \left\vert \overrightarrow{WO} \right\vert`

and we know that :

`\overrightarrow{OW} = \overrightarrow{OR} + \overrightarrow{RW}`

Then

`\overrightarrow{OW} = a +(3)/(5) \overrightarrow{OW}`

Then

`(2)/(5) \overrightarrow{OW} = a`

Then

`\overrightarrow{OW} = (5)/(2) a`
