Could use some help thanks

This problem deals with the RL circuit shown here, a series circuit containing an inductor, a resistor, and a source of electromotive force (emf), but no capacitor. The linear first-order differential equation governing the current in this circuit is given by the following. E LI' + RI = E(t) Switch NO Suppose that L = 5 H, R=25 92, and the source E of emf is an alternating-current generator that supplies a voltage of E(t) = 50 cos (40t) V. Suppose that the switch is initially in position 2, but is thrown to position 1 at R time t = 0 so that I(0) = 0. Determine the subsequent inductor current, I(t). I(t) =
