A device called a railgun uses the magnetic force on currents to launch projectiles at very high speeds. An idealized model of a railgun is illustrated in (Figure 1). A 1.2 V power supply is connected to two conducting rails. A segment of copper wire, in a region of uniform magnetic field, slides freely on the rails. The wire has a 0.92 mΩ resistance and a mass of 4.4 g . Ignore the resistance of the rails. The power supply is switched on.

Part A: What is the current?

Express your answer with the appropriate units.

Part C: What is the magnitude of the force on the wire?

Express your answer with the appropriate units.

PArt D: What will be the wire's speed after it has slid a distance of 7.0 cm?

Express your answer with the appropriate units.
