The diagram to the right shown the velocity-time graph for two masses R and S that collided elastically. Which of the following statements is true?
                     
(I) R and S moved in the same direction after the collision.
(II) Kinetic energy of the system (R & S) is minimum at t = 2 milli sec.
(III) The mass of R was greater than mass of S.
  • a)
     I only
  • b)
     II only
  • c)
    I and II only
  • d)
     I, II and III
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
The diagram to the right shown the velocity-time graph for two masses ...
  1. The velocities of both the masses are always positive hence same direction
  2. The KE will be min when Vr = Vs which is at 2ms
  3. The dpr/dt = dps/dt and as we can see in the graph dvr/dt < dvs/dt, so mass of R is greater
