(Assume all collisions to be head-on and elastic.) A particle of mass m is moving along the x-axis with speed v when It collides with a particle of mass 2m initially at rest. After the collision all the balls are at rest. Then the second ball has been projected with speed v0 towards the third ball. Mark the correct statements Five balls are placed one after the other along a straight line as shown in the figure. Initially
