Three uniform small spheres A, B and C have equal radii and masses 3 m, m and m respectively. The spheres are at rest in a straight line on a smooth horizontal surface, with B between A and C. The coefficient of restitution between each pair of spheres is e. Sphere A is projected directly towards B
with speed u.
(i) Find, in terms of u and e, expressions for the speeds of A, B and C after the first two collisions
(ii)Given that A and C are moving with equal speeds after these two collisions, find the value of e
with speed u.

if x varies inversely as p^2 and x=2 when p=4, find the formulae connecting x and p.
i was thinking this but i'm not sure.
x/p^2
2/4^2
