A100 kva, 20 kv synchronous generator is connected through a transmission line to a 100 mva, 20kv synchronous motor. the per unit transient reactances of the generator and motor are 0.25 and 0.20 respectively. the line reactance on the base of 100 mva is 0.1 per unit. the motor is taking 50 mw at 0.8 power factor leading at a terminal voltage of 20 kv. a three-phase short circuit occurs at the generator terminals. determine the transient currents in each of the two machines and in the short circuit. what is the magnitude of the current in p. u. before the short circuit occurs?

My answer is opptionc, just check with anyone else

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
