Question

How do you find the vector v with the given magnitude of 10 and in the same direction as `u=<-10,0>`?

Answer 1

`<<-10,0>>.`

Explanation:

Observe that for the given `vecu=<<-10,0>>, ||vecu||=10.`

So, if the reqd. `vecv` is such that, `||vecv||=||vecu||,` and, `vecv` and `vecu`

have the same direction, then, by the uniqueness,

`vecv=vecu=<<-10,0>>`.
