1. The total momentum of the system before and after the collision is the same.2. Yes, this supports the law of conservation of momentum.3. The final velocity of the two objects moving together is less than the initial velocity of object 1.4. The change in velocity of object 1 when the masses are equal is determined by the conservation of momentum. The sign of this change indicates the direction of the force on object 1. A free-body diagram can be drawn to visualize the forces acting on object 1.
Explicación
## Step 1The total momentum of a system before and after a collision is conserved, provided no external forces are acting on the system. This is known as the law of conservation of momentum.## Step 2The law of conservation of momentum states that the total momentum of a system remains constant if no external forces are acting on it. This means that the total momentum of the system before the collision is equal to the total momentum of the system after the collision.## Step 3When two objects with equal masses collide and move together, the final velocity of the combined object will be less than the initial velocity of the first object. This is because the kinetic energy of the system is conserved, and the kinetic energy of the combined object is less than the sum of the kinetic energies of the two separate objects.## Step 4The change in velocity of object 1 when the masses are equal is determined by the conservation of momentum. The sign of this change indicates the direction of the force on object 1. A free-body diagram can be drawn to visualize the forces acting on object 1.
