Dear Siddharth,

As to me....since the angular velocity is continously decreasing so angular acc.(a) is constant.

we know  (delta)w=at..........since w(f)=w(i) + at

hence w is proptional to t

the graph should be a straight line starting from y axis at some point and ending at x axis at some time.

Akash.
