    Do Balls X and Y Conserve Momentum and Energy in an Elastic Collision?

    Let the direction of Ux be positive and thus that of Vx is negative.

    Do Balls X and Y Conserve Momentum and Energy in an Elastic Collision?

    The conservation of momentum. It is elastic collision. Overall speeds are equivalent before and after the collision.

    Do Balls X and Y Conserve Momentum and Energy in an Elastic Collision?

    Ux- Uy = -Vx+Vy Ux- Uy = -Vx+Vy I think this is the right equation.

    Do Balls X and Y Conserve Momentum and Energy in an Elastic Collision?

    Two balls X and Y collide elastically. Their speeds before and after collision are as shown. Before After Which of the following equations is correct? A Ux +Uy = Vx +Vy B Ux +Uy = Vx - Vy C Ux - Uy = Vx +Vy D Ux - Uy = Vx - Vy
