Homework Statement
If a Mass let's say a Ball Bearing A with a velocity of 2ms-1 and a mass of 2Kg hits two other ball bearing B & C which is not moving with ball bearing B & C each has a mass of 1kg each. What will happen to ball bearing B & C?
Please see attached picture i have the question and my attempt to answer it.
Homework Equations
P= MV
or
P = Mass BallA X Velocity BallA = Mass BallB X Velocity BallB + Mass BallC X Velocity BallC
And
E = 0.5M(V)^2
The Attempt at a Solution
The collision is a Elastic Collision (The attempted answer is also in the picture.
After the collision Ball B & C will be ejected at 2ms-1 at a 45 degree angle from the point of impact with Ball A.
I know the answer is wrong as the conservation of energy is not being conserved in my answer. Can some one tell me how to answer this question correctly.
Thank you so very much.
