Two balls are suspended on parallel threads of the same length so that they touch contact each other. The mass of the first ball is

m1 = 0.2kg

and that of the second

m2 =100g

. The first ball is

deflected so that its centre of gravity rises to a height of

4.5cm

and is then released. At what

height will the balls rise to after the collision if: (i) the impact is elastic, (ii) the impact is

inelastic?
