WebIn "continuous operation mode" (current in coil never falls to zero), the output voltage of a buck converter is Vout=D*Vin, where D=50% is the duty cycle and Vin=100V. So you know that Vout=50V and thus Iout=Vout/R=5A. Next, remember the inductor equation V=L* dI/dt. V is Vin-Vout=50V. dt is the time the switch is on or off. dI is 0.2*Iout.
