I'm failing physics, today is the last day to submit all old work por favor ayudame Block X of mass mois at rest at the top of a ramp, and the block's center of mass is at a height H above the ground. Block X is then released from rest, and it slides down the ramp and collides with block Y of mass mo, which is initially at rest and has its center of mass at a height h above the ground. At the moment before the collision, block X has a speed of vo After the collision, block Y travels such that it lands at point P. Consider the block X-block Y system from the moment in time that block X is released from rest to the moment immediately after block X collides with block Y. Which of the following claims best describes the system? А Because the total momentum of the system does not remain constant, the system is open B Because the total kinetic energy of the system does not remain constant, the system is open. Because the total momentum of the system remains constant, the system is closed. D Because the total kinetic energy of the system remains constant, the system is closed.​
