Homework Statement


Two balls collide in a perfectly elastic collision. Ball 1 has a mass of 3.5kg and is initially travelling at a velocity of 5.4m/s
. It collides head-on with stationary ball 2 with mass 4.8kg. Determine the final velocity of ball 2.

Given: m1=3.5kg
vi1=5.4m/s


m2=4.8kg
vi2=0m/s

Can't read it. Momentum conservation and conservation of kinetic energy should be enough to work out this exercise. Postpone inserting numbers as long as reasonable, so you can check the relationships you get (dimension, limiting cases).
Type it out if you want more guidance (at least, from folks like me, and also from folks who don't even try to read photographed solution attempts at all).
