How Do You Calculate Vector Components of a Rocket's Velocity?

[josephcung]

A rocket heads at an angel of 40° West of North at a speed of 150 m/s.

A Draw the vector representing the planes flight and show the westward and northward components of it's velocity.

b. Calculate the westward and northward components of the plane's velocity.

Please i really need help especially with how i would have to draw.

Thank You!

Did you mix parts from two different problems in your other post?

Surely you can draw the picture yourself, can't you? Make a plus sign (+). Think of each of the four lines coming out from the center as lines on a compass. Which one will be north? Which will be west? Draw a line that is 40 degrees west from the north line.

As for the components...this involves a little bit of trigonometry. Remember [URL="https://www.physicsforums.com/insights/sohcahtoa-seemingly-simple-conceivably-complex/"]SOHCAHTOA[/url]?
