displacement

[kimikims]

Can anyone help me with these 2 problems.. I have been stuck on them :grumpy:

Thanks!

---------

A car travels 1.14km in the x- direction, then turns left 74.1 degrees to the original direction and travels an additional distance of 3.18km. Calculate the x component of the car's net displacement. Answer in units of km.

--------

A truck travels 1270m uphill along a road that makes a constant angle of 4.45 degrees with the horizontal.

1) Find the magnitude of the trucks horizontal component of displacement. Answer in units of m.

2) Find the magnitude of the trucks veritical component of displacement. Answer in units of m.

Draw a picture of the situation and add the given data (angles and distances).
Then use trigonometry. (You know, with triangles and stuff).
