Consider the diagram which shows a 2D collision between two balls of identical mass (the darker ball is initially at rest). What, if anything, is wrong with this collision? [select ALL of the correct statements from the list below] before (3 2.0 m/s C] The kinetic energy is greater after the collision C] The momentum is not conserved in the horizontal direction C] The momentum is not conserved in the vertical direction C] The kinetic energy decreases but it should not for this type of collision
