The oscillation of a body on a smooth horizontal surface is represented by the equation x= A cos omega t where x = displacement attime t, omega= frequency of oscillation. Which of the following graphs shows the corrects variation of acceleration 'a' with time 't'.

The oscillation of a body on a smooth horizontal surface is represente

1.	The oscillation of a body on a smooth horizontal surface is represented by the equation x= A cos omega t where x = displacement attime t, omega= frequency of oscillation. Which of the following graphs shows the corrects variation of acceleration 'a' with time 't'.
Answer» SOLUTION :Here `x= a COS omega t` velocity `v= -a omega sin omega t` and ACCELERATION `a= -a omega^(2) cos omega t` and graph (C ) shows the change in acceleration with time.
