Homework Statement
A 43.0 marble moving at 1.90 strikes a 30.0 marble at rest. What is the speed of each marble immediately after the collision?
(vfx)1=?
(vfx)2=?
Homework Equations
v2f=2 m1 v1 / (m1 + m2)
The Attempt at a Solution
I tried using the equation above to get the first speed and is not the right answer. I did this 1.9m/s(2(.43)/.43+.30)=2.23m/s that apparently is wrong. Any help?
