41 M In Fig. 28.31, a metal wire of mass m = 24.1 mg can slide with negligible friction on two horizontal parallel rails separated by distance d=2.56 cm. The track lies in a vertical uniform mag- netic field of magnitude 56.3 mT. At time t = 0, device G is con- nected to the rails, producing a constant current i = 35.0 mA in the wire and rails (even as the wire moves). At t = 61.1 ms, what are the wire's (a) speed and (b) direction of motion (left or right)? d m B FIGURE 28.31 Problem 41.

18. (III) An automobile traveling 95 km/h overtakes a 1.10-km- long train traveling in the same direction on a track parallel to the road. If the train's speed is 75 km/h, how long does it take the car to pass it, and how far will the car have traveled in this time? See Fig. 2-39. What are the results if the car and train are traveling in opposite directions? v = 95 km/h 1.10 km v = 75 km/h FIGURE 2-39 Problem 18.
