(i) Three balls 1, 2 and 3 lie on a smooth horizontal table. Ball 1 is given a velocity towards ball 2. Kinetic energy given to ball 1 is k_(0) . It collides with 2 and in turn ball 2 hits ball 3. All collisions are head on elastic. Masses of the balls are m, M and m respectively. (a) Calculate the kinetic energy (k_3) of ball 3 after ball 2 hits it. (b) Draw the variation of k_(3) as a function of M. (ii) Consider 10 balls laid on a smooth surface with masses m,(m)/(2),(m)/(4),(m)/(8)......(m)/(512) and first ball is pushed towards the second with kinetic energy k_(0) . [All collisions are elastic and head on]. The kinetic energy acquired by the last ball is k_(10) . In a separate experiment the 10^(th) ball is pushed towards 9^(th) ball with kinetic energy k_(0) . This time the kinetic energy acquired by 1^(st) ball is k_(1) . Compare k_(10) and k_(1)
