1. 6.3 Vectors Continued
Part 2: Applications
Vectors: __________ and ____________

2. Ex. 1) Find the component form of the
vector that represents the velocity of an
airplane descending at a speed of 100 miles
per hour at an angle of 23° below the
horizontal.

3. Ex. 2) An airplane is traveling at a speed of 724
kilometers per hour at a bearing of N 30° E. If the wind
velocity is 32 kilometers per hour from the west, find the
resultant speed and direction of the plane.

4. Ex. 3) Three forces with magnitudes of 75
pounds, 100 pounds, and 125 pounds act on an
object at angles of 30°, 45°, and 120°,
respectively, with the positive x-axis. Find the
direction and magnitude of the resultant of
these forces.
