north 990 sin 45 = y component
west 990 cos 45 = NEGATIVE x component
south is -990 y component
and zero x component
On the map, let the +x-axis point east and the +y-axis north.
A)An airplane flies at 990 km/h northwestward direction (i.e., midway between north and west). Find the components of its velocity.
B)Repeat for the case when the plane flies due south at the same speed.
To find the average velocity component to the east, for example, you need to find the distance traveled to the east, and divide by the TOTAL time. To find the average speed, you need to add the distance traveled to the east, and the distance traveled to the north, and divide by the total time.
