Three particles of equal masses are placed at the corners of an equilateral triangle as shown in the figure. Now particle `A` starts with a velocity `v_(1)` towards line `AB`, particle `B` starts with a velocity `v_(2)` towards line `BC` and particle `C` starts with velocity `v_(3)` towards line `CA`. The displacement of `CM` of three particle `A, B` and `C` after time `t` will be (given if `v_(1)=v_(2)=v_(3))`

Let there are three equal masses situated at the vertices of an equilateral triangle, as shown in Fig. Now particle A starts with a velocity v_(1) towards line AB , particle B starts with the velocity v_(2) , towards line BC and particle C starts with velocity v_(3) towards line CA . Find the displacement of the centre of mass of the three particles A, B and C after time t . What would it be if v_(1)=v_(2)=v_(3) ?
