The figure gives the linear momentum versus time for a particle moving along the x-axis. A force directed along the x-axis acts on the particle. Compare the magnitudes of the forces.

  1. F1 > F2 > F3 > F4
  2. F1 > F3 > F2 = F4
  3. F4 > F3 > F2 > F1
  4. F3 > F1 > F4 = F2
  5. none of the above statements is true.
