Question

It is approximately 3000 km from Portland to Houston. It is approximately 5500 km fromAnchorage, Alaska to Houston. A plane flies in a straight line from Houston to Anchorageand during the flight it passes directly over Portland. Find a vector which describes thedisplacement of the plane.

Answer 1

vector = -
`\vec v` + 2500

Step-by-step explanation:

given data

Portland to Houston = 3000 km

Anchorage, Alaska to Houston = 5500 km

solution

we take here vector displacement from Portland to Houston is =
`\vec v`

and

vector displacement from Houston to Portland is = -
`\vec v`

so that here displacement from Houston to Anchorage, Alaska is

vector = -
`\vec v` + 2500
