Engineer IN is designing a magnetic launcher. Using this launcher, a conducting rod (mass =1.2m=1.2 g and resistance R=0.17) is propelled along parallel conducting (resistanceless) rails (width =0.21d=0.21 m). A significant constant magnetic field B=2.1 T is directed downward perpendicular to the plane of the rails of the launcher. At the end of the rails, between them, there is a battery with a source voltage of V0=46 V, discharging current counterclockwise when viewed from above. The conducting rod starts from rest. Air resistance is neglected.

Calculate:

a) the maximum velocity attained by the launcher.

Vmax

b) the acceleration of the conducting rod at t=1.1 ms.
