Need help with Physic assignment

Question

1. Draw and label the following directional vectors.
2. 20 degrees North of West
3. 40 degrees East of South
4. 30 degrees South of West
5. 10 degrees West of North
6. 15 degrees North of East
7.  Find the x and y  components of a position vector that has a magnitude of      r = 75. 0 m and an angle related to the x axis of (a) 35.0° and (b) 65.0°.

1.  Find the x and y components of a velocity vector that has a magnitude of       r = 15.5 m/s and an angle related to the x axis of (a) 10.0° and (b) 70.0°. 

1.  Find the x and y components of a displacement vector that describes your motion if you travel 20 m along an escalator at an angle of 25.0° above the horizontal.

Answer 1

2) the x-component is r•cos(θ) = (for problem a) 75cos(35°) which you can plug in your calculator to get 61.4 m. The y-component is r•sin(θ)

For the other problems, use the same relationship, the x-component of the velocity vector is 15.5cos(10°) and the y-component is 15.5sine(10°). Of course you plug those into your calculator to get a number. To get the answer for 70°, just plug in 70° instead of 10°.

Same as above for the displacement, the x-component is 20cos(25°)
