I just started a physics class and im totally confused, here's my problems for tonight if anybody can help it would be greatly appreciated. Im not necessarily looking just for answers but help getting them too:

1. A car is driven 130 km west and then 55 km southwest. What is the displacement of the car from the point of origin (magnitude and direction)?

Magnitude: (km)

Direction: (° south of west )

2. A delivery truck travels 21 blocks south, 17 blocks east and 18 blocks north. What is its final displacement from the origin? Assume the blocks are equal length.

Magnitude: 17.3 blocks (i figured that part out)

Direction: ° (counterclockwise from east is positive)

3. Vector V1 is 8.17 units long and points along the -x axis. Vector V2 is 4.58 units long and points at +35.0° to the +x axis.

(a) What are the x and y components of each vector?

V1x=

V1y=

V2x=

V2y=

(b) Determine the sum V1 + V2.

Magnitude:

Direction: ° (counterclockwise from the +x axis is positive)

4. An airplane is traveling v = 810 km/h in a direction 38.5° west of north.

(a) Find the components of the velocity vector in the northerly and westerly directions.

____ km/h (north)

____ km/h (west)

(b) How far north and how far west has the plane traveled after 7 h?

____ km/h (north)

____ km/h (west)
