An 8.0 kg ball travelling at 4m/s collides head on with a 3kg ball travelling at 14m/s . The balls bounce off each other and travel back the way they came. The 8.0 ball away at 2m/s . Calculate the velocity of the 3kg ball after the collision

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
