What is the key concept to consider when analyzing the momentum and energy of the clay block system after the collision?

• The external forces acting on the system

• The total mechanical energy of the clay block system

• The angular momentum of the clay block system about the top of the string

• The linear momentum of the clay block system

When two people of different masses push off each other on ice, which of the following is true?

• The momenta of the two people are of equal magnitude

• The kinetic energies of the two people are equal

• The speeds of the two people are equal

• The less massive person has a smaller initial acceleration

What is the relationship between force and acceleration when two objects of different masses push off each other?

• The object with smaller mass will have a smaller acceleration

• Both objects will have the same acceleration

• The object with smaller mass will have a greater acceleration

• The object with greater mass will have a greater acceleration

In a collision where two blocks stick together, what happens to the kinetic energy of the system?

• It remains the same because the collision is instantaneous

• It increases because the blocks have the same velocity after the collision

• It decreases because some kinetic energy is transformed into internal energy

• It remains the same because there is no friction

How does the change in velocity of the blocks help determine which block has greater mass?

• The block with the greater change in velocity has the smaller mass

• The block with the smaller change in velocity has the greater mass

• The block with the greater change in velocity has the greater mass

• The block with the smaller change in velocity has the smaller mass
