Momentum and CollisionHard
Question
The diagram shows the velocity - time 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. The velocities of R and S were at the time of the collision.
III. The mass of R was greater than mass of S.
I. R and S moved in the same direction after the collision
II. The velocities of R and S were at the time of the collision.
III. The mass of R was greater than mass of S.
Options
A.I only
B.II only
C.I and II only
D.I, II and III only
Solution
COLM : mR (0.8) + mS (0) = mR(0.2) + mS(1.0) ⇒ 0.6 MR = mS mR > mS
