Cart X travels in the positive direction along a horizontal
surface, and cart Y travels in the positive direction. The
carts collide, and a student collects data about the carts'
velocities as a function of time before, during, and after a
collision, as shown. The masses of both objects are
known. Which of the following best indicates how the
student should use the graph to determine whether the
collision is elastic or inelastic and provides a correct
justification? - Answer-Using the known mass and known
velocity for each cart to determine the kinetic energy of the
system before and after the collision, because the kinetic
energy changes in an inelastic collision
In an experiment, two objects, Object X and Object Y,
travel toward each other and collide. Data are collected
about each object before, during, and after the collision to
create a graph that shows the momenta of Object X and
Object Y as a function of time. How should a student use
the data found on the graph to verify the conservation of

momentum? - Answer-The vector sum of the momenta
should be compared, because momentum is a vector
quantity.
A student must conduct an experiment to verify the
conservation of momentum. Cart X and Cart Y travel
toward each other and eventually collide, as shown in the
figure. The student has access to the two carts, one mass
balance, and two motion detectors. If the mass of each
cart is known, how should the student arrange one or both
motion detectors so that the student can collect enough
information about the motion of the carts, in order to verify
the conservation of momentum of the system? - Answer-
Correct. To verify the conservation of momentum, the
momentum of the system before the collision should be
the same as the momentum of the system after the
collision. Therefore, a student must measure the initial
velocities of Cart XX and Cart YY and the final velocities of
Cart XX and Cart YY. This combination of motion detectors
and their positions will allow for the velocities of each
object to be measured before, during, and after the
collision. (two sensors on the outsides)
A student conducts three experiments in which two carts,
cart 1 and cart 2, travel toward each other and collide. A
, 3|Page
graph of each cart's momentum as a function of time is
shown above. In which experiment, if any, does the graph
indicate the presence of a net external force exerted on
the two-cart system? - Answer-None
A student conducts an experiment to verify whether
momentum is conserved for a situation in which a collision
occurs. The two objects, Object X and Object Y, travel
toward each other, as shown in Figure 1. After the
collision, the two objects travel as shown in Figure 2. Data
collected from three trials of this experiment are shown in
the table. Which of the following statements is correct
based on the data? - Answer-The conservation of
momentum can be verified within the threshold of
experimental uncertainty.
A student must conduct an experiment in which an elastic
collision occurs. In the experiment, Block X of mass 2kg
travels with a velocity vX in the positive direction toward
Block Y of mass 2kg that is at rest, as shown in Figure 1.
After the collision, Block Y travels in the positive direction
with velocity vY while Block X remains nearly at rest. Data
collected of the initial and final velocities of both blocks for
three trials of the experiment are shown in the table. Did
the student conduct an experiment in which an elastic
