How do you do ranges for coefficient of restitution? i know you have to work it out by doing inequalities but how? here is an example for june 2001 paper.

a particle A of mass 2m is moving with speed 2u on a smooth horizontal table. the particle collides directly with a particle B of mass 4m moving with speed u in the same diresction as A. the coefficient of restitution between A and B is 1/2.

(a)show that the speed of B after the collision is 3/2u.(i have done this part)

(b)Find the speed of A after the collision.(i have done this as well,answer=u)

Subsequently B collides directly with a particle C of mass m which is at rest on the table. the coefficient of restitution between B and C is e. Given that there is no further collisions,

(c)Find the range of possible values for e.(the answer is e is less than or the same as 2/3)

please can some one help

well, for no other collisions, C > B > A

(think about it for a sec)

so do something do with that.

i always think i know what im doing but htne they do something else though, so it may not be right.
