Question as follows:



“A ball of mass m moving with speed kV on a smooth table catches up and collides with another ball of mass λ m moving with speed V travelling in the same direction on the table. The impact reduces the first ball to rest.
Find the coefficient of restitution in terms of k and λ ”



My working is as follows:
question working



The ‘before = after’ section is in reference to the momentum.



Have I so far done something incorrect? Or, is my method even correct? The answer to the question seems nearly impossible to achieve considering the path the working is currently going on.
