Question

Vector C is 6.28 units long in a105° direction. In unit vectornotation, this would be writtenas:C = [?]î + [?]i coefficient (green)j corfficient (yellow)

Answer 1

We have a vector 6.28 units long in 105° direction

`\begin{gathered} 6.28\cos (105)=-1.62 \\ 6.28\sin (105)=6.03 \end{gathered}`

Therefore the vector C is

`\vec{C}=-1.62i+6.03j`
