Laws of Motion question

2011 · Q150

NEETPhysicsLaws of MotionMCQ+4 / −1
A body of mass M hits normally a rigid wall with velocity V and bounces back with the same velocity. The impulse experienced by the body is
  1. A
    MV
  2. B
    1.5 MV
  3. C
    2MV
  4. D
    zero
View written solutionFree

Correct answer: C

Impulse experienced by the body = change in momentum
= MV – (–MV)
= 2MV.
