Constants Part C A Conducting Bar With Mass M And Length L Slides Over Horizontal Rails That Are Connected To A Voltage 1 (86.05 KiB) Viewed 36 times

Constants Part C A conducting bar with mass m and length L slides over horizontal rails that are connected to a voltage source. The voltage source maintains a constant current I in the rails and bar, and a constant, uniform, vertical magnetic field B fills the region between the rails (see the figure (Figure 1)). If the bar has mass m, find the distance d that the bar must move along the rails from rest to attain speed v. Express your answer in terms of the variables 1800 A , 45 cm, v, 29 kg , and 0.76 T.

Part D It has been suggested that rail guns based on this principle could accelerate payloads into earth orbit or beyond. Find the distance the bar must travel along the rails if it is to reach the escape speed for the earth (11.2 km/s). Let B = 0.76 T, I = 1800 A, m = 29 kg, and L = 45 cm. For simplicity, assume the net force on the object is equal to the magnetic force, as in parts A and B, even though gravity plays an important role in an actual launch into space.
