### Vector Problems in Airplane Navigation#### Problem 2.18:A plane flies for 3 hours and reaches a point 600 km north and 800 km east of its starting point. Find the direction and magnitude of its average velocity.#### Problem 2.19:A plane flies south at 500 km/h for 2 hours and then flies west at 500 km/h for 1 hour. 1. What is its average speed?2. What are the magnitude and direction of its average velocity?---### Solution Explanation:For Problem 2.18:- **Direction and Magnitude Calculation**: This involves using Pythagorean Theorem to calculate the magnitude of velocity vector and trigonometric functions to find the direction.For Problem 2.19:- **Average Speed Calculation**: This can be found by dividing the total distance traveled by the total time.- **Magnitude and Direction of Average Velocity**: This involves finding the resultant displacement vector and using it to calculate the average velocity. These problems help in understanding the concepts of vectors, magnitudes, and directions, crucial for navigation and related physics problems.

Part 10 of 11 - Determining Total Time of Flight As a challenge, Joey asks Meixiu how she can use v, = v, sin 0, - gt to find the total time of flight for the baseball. Which of Meixiu's responses is correct? ] "At the top of the baseball path the vertical component of the velocity is zero, so I will set v, = 0. Then I can solve the equation for t, the time for the upward portion of the path, and double it to find the total time of flight."

2. The compass of an aircraft indicates that it is headed due north, and its airspeed indicatorshows that it is moving through the air at 120 miles per hour (that is, the velocity of the aircraftrelative to the air is 120 mi hr -1 ). If there is a wind of 50 miles per hour from west to east (thevelocity of the air is 50 mi hr -1 east),(a) what is the velocity of the aircraft relative to the ground?(b) in what direction should the pilot head in order to travel due north relative to the ground?
