Two balls with the same mass move in the direction of one another. Ball 1 moves in the positive x- direction with speed of ₁. and ball 2 moves in the negative x-direction with a speed of V2. The balls collide elastically, and both change direction after the collision. Write an expression for the horizontal component of the system's initial momentum, Pix, in terms of mass m, P₁, and vi Write an expression for the horizontal component of the system's final momentum, Pf.x, in terms of m and the final speeds of ball 1, P₁, and ball 2, P₂f- If the initial speeds of the balls were ₁2.0 m/s and v2=1.0 m/s what would be the final speed and direction of ball 2, P27, in meters per second?

Two balls with the same mass move in the direction of one another. Ball 1 moves in the positive x- direction with speed of V₁, and ball 2 moves in the negative x-direction with a speed of 2;. The balls collide elastically, and both change direction after the collision. Y Write an expression for the horizontal component of the system's initial momentum, Pix, in terms of mass m, V₁i, and v₂i- Write an expression for the horizontal component of the system's final momentum, prx, in terms of m and the final speeds of ball 1, V₁f, and ball 2, ₂f- If the initial speeds of the balls were ₁ = 2.0 m/s and v2 = 1.0 m/s what would be the final speed and direction of ball 2, V2r, in meters per second?
