Vector Addition B and C 02 - Two Walks A walker first walksalong Vector π΅β . Then he changes his direction and walks alongVector πΆβ . Their magnitudes are: B=3 km C = 3.4 km, the angles inthe figure are: π½ = 29.0Β°, πΎ = 19.0Β°, He realizes that he is lostand calls you to rescue him. In order to take the shortest path torescue the walker, you use what you learned in this course tofigure out the walkerβs current location (including how far away heis from the starting point and the direction).
Draw a vector from the walker's starting point (the origin) tohis current location after the two walks. Label this vector
π β What is the relationship among vectors π΅β,πΆβ and π β?
Use what you have learned about vector addition to find themagnitude and the direction of vectorπ β
.A. The magnitude (in km) of π β is
B. Find the direction (in degrees) of the vector π β
The direction is represented by a counterclockwise angle fromthe +xaxis.
C. If you need to reach the walker's current location in 10minutes, what should be your speed in m/s?
