单选题 A particle is suspended from a post on top of a cart by a light string as shown in Figure. The cart and particle are initially moving to the right at constant speed v, with the string vertical. The cart suddenly comes to rest when it runs into and sticks to a bumper. Which of the following statements is true about the collision process?
