(adsbygoogle = window.adsbygoogle || []).push({}); kinetic energy question!!

hey,

I have the following question to complete, and dont have the slightest clue where to start! :(

A sphere of mass 1kg, moving at 10 m/s, overtakes another sphere of

mass 5 kg moving in the same line at 3m/s. Find the loss of kinetic

energy during impact, and show that the direction of motion of the

first sphere is reversed. Assume the coefficient of restitution e = .75

should i use the following forumla?: 2(m1 + m2)E = m1m2(u1-u2)2(1-e2)

any help would be greatly appreciated,

Rich
