Consider a weight suspended from a string wrapped around the hub of a flywheel. When the weight is released, the flywheel and hub rotate together about the fixed axis O. If the hanging weight is 30.0 N, the radius of the hub(r)is 20.0 cm, and the moment of inertia of the flywheel is 24 kgm2, calculate the torque and angular acceleration of the flywheel.

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. 

Simple, don't do it. just don't go to that dock

C. the electric current passes from the slip rings, through the brushes, and to the collection device.
