Vector Analysis using Graphical and Analytical

[zbam]

1.a A hot air balloon drifts 12km in a direction 70 degrees South of East. An abrupt charge in air movement then comes the balloon 8.0km in a direction 40 degrees South of West. Estimate the record displacement from the starting position after the two drifts. (magnitude & displacement)

1.b A car travels 200 km west, 100km at an angle 60 degrees South of East. What is the net displacement of the car?



2. I will use graphical and for the analytical method, i will use trigonometric function.



3. trigonometric functions-sine, cosine & tangent


Please help me on how to graph it and how to solve for the analytical method. Thanks!

Hi zbam and welcome to the forums,

Do you have no idea at all of how to start these problems?

thanks, I have no idea, the graphical method is easy but I forgot it.

Okay, the graphical method and the analytical method are very similar (except you need to be more accurate in you sketch for the graphical method). Start by drawing a diagram of what is happening, draw the two drifts as vectors, noting their magnitude as direction.
