Could you please explain this momentum question? texbook page 155, qn 8 1. Block X of mass m is at rest at the top of a ramp, and the block's centerof mass is at a height H(1) above the ground. Block X is then released fromrest, and it slides down the ramp and collides with block Y of mass m,which is initially at rest and has its center of mass at a height h above theground. At the moment before the collision, block X has a speed of v. Afterthe collision, block Y travels such that it lands at point P. Consider the blockX-block Y system from the moment in time that block X is released fromrest to the moment immediately after block X collides with block Y. Whichof the following claims best describes the system? Treat friction and airresistance as negligible. *Block XmoBlock YmoH,O (A) The system is open since the total momentum of the system changes.(B) The system is open since the total KE of the system changes.O (C) The system is closed since the total momentum of the system remains constaO (D) The system is closed since the total KE of the system remains constant.

Consider the total energy E of the system at three instants of time. Consider an elastic collision…

A 10.0-kg bob is attached to a rod whose length is 10.0 m. The right end of the rod is fixed, and the bob is released from rest. a) Determine the speed of the bob when it is below the pivot point (vertical angle is zero). b) Determine the tension in the rod when the bob is below the pivot point. hint: to determine the speed of the bob when it is below the pivot point, you will need to use Calculus.
