A particle moves along the x - axis according to `x = A[1 + sin omega t]`. What distance does is travel in time interval from `t = 0` to `t = 2.5pi//omega` ?A. `4A`B. `6 A`C. `5 A`D. `3 A`

Answer» Correct Answer - C
`t = (2.5 pi)/(omega) = (2.5 pi)/(2pi//T)`
`= (2.5)((T)/(2))`
`= 5((T)/(4))`
Particle starts from extreme position and in every
`(T)/(4)` time it travels a distance `A`. So, in time
`t = 5(T//4)` it will travel a distance `5A`.
