I just started a physics class and I am totally confused, here's my problems for tonight if anybody can help it would be greatly appreciated. I am 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)
