A man walks 2.05 km north and then 2.75 km east, all in 2.20 hours. (a) What is the magnitude (in km) and direction (in degrees north of east) of his displacement during the given time? magnitude 3.43 Draw a diagram of the two displacement vectors along both legs of the trip, placed tip to tail. Note they form a right angle. How is the net displacement vector related to these two vectors? What is the Pythagorean theorem? km direction Draw a diagram of the net displacement vector. Note the angle is defined to be north of east. What trigonometric function can you use to find the angle? . north of east What is the magnitude (in km/h) and direction (in degrees north of east) of his average velocity during the given time? magnitude 1 56 What is the magnitude of the displacement vector? How is the average velocity related to the displacement and time? km/h direction 36 70 If the average velocity vector is the displacement vector divided by time, how should the directions of the average velocity and displacement be related? . north of east (c) What was his average speed (in km/h) during the same time interval? km/h
