Question

How do you find the component form of v given its magnitude 7/2 and the angle it makes with the positive x-axis is `theta=150^circ`?

Answer 1

Component form of `v` is `(-3.03, 1.75)`

Explanation:

`r=7/2=3.5 , theta= 150^0`

Component form of `v` along `x` axis is `r cos theta = 3.5 cos 150 ~~ - 3.03 (2dp)` and

Component form of `v` along `y` axis is `r cos theta = 3.5 sin 150 =1.75` and

Component form of `v` is `(-3.03, 1.75)` [Ans]
