Question
(b) A particle moves to the left (-x-direction) in free space. A set of snapshots is taken. You observe that the partide has changed location by unequal amounts in each snapshot. The snapshots show the change in the particle's locations are decreasing. (i) What is true about the partide's average momentum vectors? (Select all that apply.) As time elapses, the average momentum vectors are decreasing in magnitude. The average momentum vectors point in the +x direction. a The average momentum vectors point in the -x direction. Cannot determine information about the average momentum vectors. The average momentum vectors are constant vectors. As time elapses, the average momentum vectors are increasing in magnitude. The average momentum vectors have zero magnitude. (ii) What is true about the change in the particle's average momentum vectors? (Select all that apply.) s The change in the average momentum vectors point in the -x-direction. a The change in the average momentum vectors point opposite the direction of the average momentum vectors. The change in the average momentum vectors is zero. The change in the average momentum vectors point in the +x-direction The change in the average momentum vectors point in the same direction as the average momentum vectors. (iii) What is true about the average net force acting on the particle? (Select all that apply.) The net force points in the same direction as the change in the average momentum vectors. The net force points in the opposite direction of the average momentum vectors. There are no forces acting on the particle. The net force acting on the particle points in the x-direction. The net force points in the same direction as the average momentum vectors. There is no net force acting on the particle. The net force points in opposite direction of the change in the average momentum vectors. The net force acting on the particle points in the -x. rection.Explanation / Answer
ii)
change in average momentum vectors points in +X direction
change in momentum vectors point in the opposite direction as the average momentum vectors.
iii)
net force points in same direction as the change in average momentum vectors
the net force points in +Ve X direction
