Given the magnitude and direction of a vector, find its components.

Question

|v| = 5.10; (theta) = 168.69

Given the magnitude and direction of a vector, find its components.

Answer 1

cos 168.69 = x / 5.1

5.1 cos 168.69 = x

-5.00096 = x

sin 168.69 = y / 5.1

5.1 sin 168.69 = y

1 = y

<-5, 1>
