Q2
Three identical balls P1,P2 and P3 are placed on a frictionless surface in a straight line. The mass of each is m. Another ball P moving with velocity v collides directly with the three balls as shown in figure. The collision is perfectly elastic; now determine the velocity of all the four balls.

Q5
A ball of mass m moving with velocity V makes a head on elastic collision with a ball of the same mass moving with velocity 2V towards it. Taking direction of V as positive velocities of the two balls after collision are
