Two Masses Collide and Stick Together

question 5

Multiple Choice

Two masses collide and stick together.Before the collision one of the masses was at rest.Is there a situation in which the kinetic energy is conserved in such a collision?

• A)Yes,if the less massive particle is the one initially at rest.
• B)Yes,if the more massive particle is the one initially at rest.
• C)Yes,if the two particles have the same mass.
• D)No,kinetic energy is always lost is such a collision.
