Tricky Problem

Classical Mechanics Level 3

A particle is moving along $x$ -axis whose acceleration is given by $a=3x-4$ , where $x$ is the position of the particle.At $t=0$ the particle is at rest at $x=\dfrac43$ .The distance covered by the particle in $5\text{ s}$ is:

2\text{ m}

6\text{ m}

4\text{ m}

0\text{ m}

According to the question at t=0,the particle is at rest that means the velocity of the particle is 0 and according to the question at t=0,x=4/3.Put the value in the given equation and then you will find the acceleration =0. That means the particle has velocity,v=0 and acceleration,a=0.So,the particle is always at rest.So the distance covered by the particle by 5s is 0m.
