help me solve these questions:

wueston 1o Velocity of Object X Before Collision Velocity of Object Y Before Collision Velocity of Object X After Collision Velocity of Object Y After Colli 4v, -y m 3 P 3 Object X of mass M travels toward object Y of mass 2M in such a way that they collide. The table contains data about the velocities of object X and object Y immediately before the collision and immediately after the collision. What are the change in momentum of the two-object system and the change in momentum of each object from immediately before the collision to immediately after the collision? @ Change in Momentum of the System Change in Momentum of Object X Change in Momentum of Object Y 10Mvy 10Mw, Zero g e Change in Momentum of the System Change in Momentum of Object X Change in Momentum of Object Y 10 Mo 10 Mo Zero T - Tn Change in Momentum of the System Change in Momentum of Object X Change in Momentum of Object Y 20Mu, 10Mvy 10Mv, 3 = a 3 @ Change in Momentum of the System Change in Momentum of Object X Change in Momentum of Object Y Zero Zero Zero Question 16 A student drops an object from rest above a force plate that records information about the force exerted on the object as a function of time during the time interval in which the object is in contact with the force plate. Which of the following measurements should the student take, in addition to the measurements from the force plate, to determine the change in momentum of the object from immediately before the collision to immediately after the collision? @ The mass of the object The final speed of the object The distance fallen by the object The student has enough information to make the determination. Question 18 A student must determine a nonzero change in momentum of an object for a specific interval of time. Which of the following experiments could the student conduct? Select two answers. A Drop a ball of known mass above a motion detector, and record the final speed of the ball before it reaches the motion sensor. B Drop a coffee filter of known mass from a known height above a motion sensor, and record the terminal speed of the coffee filter as it falls. Pull a block of known mass across a rough surface with a spring such that the block travels at a constant speed for 5 s as measured by a stopwatch. Record the force necessary to pull the block at a constant speed. Give a block of known mass an initial velocity so that it slides across a rough surface in front of a motion detector, slows down, and eventually stops. Use the motion detector to record the initial velocity of the block
