The equation of motion of a particle is x=acos(alphat)^(2). The motion

1.	The equation of motion of a particle is x=acos(alphat)^(2). The motion is
Answer» PERIODIC but not oscillatory periodic and oscillatory oscillatory but not periodic Neither periodic nor oscillatory. Solution :GIVEN `x=acos(alphat)^(2)=acosalpha^(2)t^(2)` as the equation of motionn INVOLVES COSINE function and `t^(2)` HENCE it is oscillatory but not periodic.
