# How do i calculate change in velocity?

## Homework Statement

An airplane is flying at 2.00 x 10^2 km/h [S30.0W]. It makes a smooth wide turn and heads east at 2.00 x 10^2 km/h. Find its change in velocity.

v = vf - vi

## The Attempt at a Solution

the directions are throwing me off. What do i do after i draw it out? Can you guys tell me the answer plz? so I can make sure I did the question right

thank you if you can help.

No, we cannot tell you the answer. I did write out suggestions as to how to do vector problems in general and then looked at the directions given here!

Initially, the airplane was flying at 200 miles per hour due west It turned around and is flying at 200 miph due east. If you were to write "200 miles per hour due west" as +200 mph, what would "200 miles per hour in the opposite direction" be?

theres is [S30.0W] and then it turns to east.... how do i calculate with this weird angle in the question?
