A student conducts an experiment to verify that a collision is elastic. The two objects, object X and object
Y, travel toward each other, as shown in the figure. The mass and the initial speed of both objects are
known. Which of the following equations should the student consider using to verify that the collision is
elastic, and why?
Equation I: Ap = F At
Equation I Σ Σ
Equation III: AK = K¡ – Ko

Equation I only, because the change in momentum of object X will be equal to the
negative change of momentum for object Y.
Equation II only, because the conservation of momentum must be verified for the system
of object X and object Y.
Equation I and equation III, because the change in momentum of object X will be equal
to the negative change of momentum for object Y, and the difference in the kinetic energy
of the system before and after the collision should be determined.
Equation II and equation III, because the conservation of momentum must be verified for
the system of object X and object Y, and the difference in the kinetic energy of the
system before and after the collision should be determined.
