When the simulation is run a constant force directed right is applied to ball 1 (the ball on the left) for 0.2 seconds. Choose all the correct statements about this situation from the list below. Note that "the total mass of the system" is defined as the sum of mass 1 and mass 2, and "the total momentum of the system" is the same as the momentum of the center-of-mass.

The velocity of the center-of-mass that the system has after the applied force is turned off depends only on the applied force and does not depend on what the two masses are set to.

Once the applied force is removed the total momentum of the system is constant and, at every point in time, is always equal to the vector sum of ball 1's momentum plus ball 2's momentum.

Once the applied force is removed the velocity of the center-of-mass of the system is constant and, at every point in time, is always equal to the vector sum of ball 1's velocity plus ball 2's velocity.

If the applied force is unchanged, increasing the total mass of the system will increase the total momentum the system has after the applied force is turned off.

Because the force is applied to ball 1, the total momentum the system has after the force is removed depends much more on the mass of ball 1 than it does on the mass of ball 2.

If the applied force is unchanged, increasing the total mass of the system will increase the velocity the center-of- mass of the system has after the applied force is turned off.

The total momentum the system has after the applied force is turned off depends only on the applied force and does not depend on what the two masses are set to.

Note that the spring connecting the balls is assumed to have no mass. Given the limits on the sliders available to you in the simulation determine (after the force has been removed)

(a) The largest possible value of the magnitude of the velocity of the center-of-mass of the system.
(b) The smallest possible non-zero value of the magnitude of the momentum of the center-of-mass of the system.

(a) Number Units
(b) Number Units
