Three blocks are initially placed as shown in the figure. block A has mass m and initial velocity v to the right. Block B with mass m and block C with mass 4m are both initially at rest. Neglect friction. All collisions are elastic. The final velocity of block A is

(Assume all collisions to be head-on and elastic.) 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
