which graph represents the angular velocity as function of time in which the magnitude of angular velocity is contiguously decreasing? a) upward curve from origion with w on y axis and time on x axis b)upward straight line from constant on y axis c)downward straight line from constant on yaxis d) down parabola from origion

the answer is option (d)that is down parabola from origin

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.
