A particle is moving along the x-axis whose acceleration is given by ` a= 3x-4`, where x is the location of the particle. At t = 0, the particle is at rest at `x = 4//3m`. The distance travelled by the particles in 5 s is

A

zero

B

42 m

C

Infinite

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
a. At `t = 0 , v=0, x = 4//3m`
`a = (4xx3)/3 - 4 = 0`
As both the particle velocity and acceleration are zero at t = 0,
it will always remain at rest and hence distance travelled at any
time interval would be zero.
