The equation of motion of a particle is ...

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

A

periodic but not oscillatory

B

periodic and oscillatory

C

oscillatory but not periodic

D

Neither periodic nor oscillatory.

Text Solution

Verified by Experts

The correct Answer is:
C
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.
