Two blocks of masses of 0.2 kg and 0.5 k...

Two blocks of masses of `0.2 kg` and `0.5 kg` which are placed `22m` apart on a horizontal surface `(mu = 0.5)` are acted uponby two forces of magnitude `3 N`each as shown in figure in time `t = 0` Then the time t at which they collide with each other is
