A disc which is at rest started to spin about a stationary axis The angular acceleration of the disc is given by a 20 rad s where is the angle of rotation of disc from its Initial position Which of the following graphs correctly represents the variation of angular velocity with respect to 0 w rad s A B OC D co rad s w rad s w rad s V Solution B w K Given a 20 We know a dw do wdw 20d0 1 20 w dw dt 0 rad 9 rad 0 rad 8 rad Integrating on both sides So wdw f20d0 0 dw do Xx do dt
