Electrons move through a certain electric circuit at an average speed of 1.1 1022 m/s. How long (in minutes) does it take an electron to traverse 1.5 m of wire in the filament of a light bulb?
4. Two geological field teams are working in a remote area. A global positioning system (GPS)
tracker at their base camp shows the location of the first team as 38 km away, north of
198
west, and the second team as 29 km away, east of north. When the first team uses its
358
GPS to check the position of the second team, what does the GPS give for the second
team’s (a) distance from them and
(b) direction, measured from due east?

How long (in minutes) does it take an electron to traverse 1.5 m of wire in the filament of
a light bulb?
5. The data in the following table represent the initial and final velocities for a boat traveling
along the x axis. The elapsed time for each of the four pairs of velocities in the table is 2.0
s. Review the concept of average acceleration in Section 2.3 and then determine the average
acceleration (magnitude and direction) for each of the four pairs. Note that the algebraic
sign of your answers will convey the direction.
Initial velocity v Final velocity v
0
(a) 12.0 m/s 15.0 m/s
(b) 15.0 m/s 12.0 m/s
(c) 26.0 m/s 23.0 m/s
(d) 14.0 m/s 24.0 m/s
