V⃗ 1 and V⃗ 2 are different vectors with lengths V1 and V2 respectively. Find the following:?

Express in terms of V⃗ 1

Answer 1

1)
(V1)²

2)
The scalar product of the 2 vectors in terms of V1 and V2 would be
(V1)(V2)cosθ

When the 2 vectors are parallel to each other, θ = 0, so cosθ = 1. The scalar product would then be
(V1)(V2)
