Conservation of momentum in two dimensions

Example 1: 2D conservation of momentumQuestion

In a rugby game, Player 1 is running with the ball at 5 m·s−1 straight down the field parallel to the edge of the field. Player 2 runs at 6 m·s−1 an angle of 60° to the edge of the field and tackles Player 1. In the tackle, Player 2 stops completely while Player 1 bounces off Player 2. Calculate the velocity (magnitude and direction) at which Player 1 bounces off Player 2. Both the players have a mass of 90 kg.
