Question

A jet is flying at 350 miles/hour in still air. It is traveling in the direction of 210°, where 90° represents North. Find the component form of vector r, which represents the jet's motion.

Answer 1

Explanation:

Answer 2

`r_x=-175√(3)mph`

`r_y=-175mph`

Explanation:

we are given

A jet is flying at 350 miles/hour in still air

so, we get

`|r|=350`

It is traveling in the direction of 210°

so, we get

`\theta=210`

now, we can use component formula

`r_x=|r|cos(\theta)`

now, we can plug values

`r_x=350cos(210)`

`r_x=-175√(3)mph`

`r_y=|r|sin(\theta)`

now, we can plug values

`r_y=350sin(210)`

`r_y=-175mph`
