Particle A is moving along X-axis. At time t = 0, it has velocity of `10 ms^(-1)` and acceleration `-4ms^(-2)`. Particle B has velocity of `20 ms^(-1)` and acceleration `-2 ms^(-2)`. Initially both the particles are at origion. At time t = 2 distance between the particles are at origin. At time t = 2 s distance between the particles is
