Part 1 - Application An airplane is flying on a bearing of 170 at 495 mph. Find the component form of the velocity of the airplane. Be sure to show and explain your work.

Part 2 - Find the error(s) and solve the problem correctly. Be sure to show and explain your work. An airplane is flying on a compass heading (bearing) of 170 at 460 mph. A wind is blowing with the bearing 200 at 80 mph. a. Find the component form of the velocity of the airplane. b. Find the actual ground speed and direction of the airplane Answer: a. v = 460 = < -453.01, 79.88 > b. Find the wind vector w = 80 = <-75.18, -27.36> Velocity vector = v + w = < -528.19, 52.52> Actual speed | |v + w| | ( 528. 19) 530.79 mph

2 + (52. 52) 2 Actual direction: = 180 + tan )= 95.68

Part 3 - Discussion Question What determines when you can use the Law of Sines or the Law of Cosines? Sketch an example of your explanation.
