Consider a sphere of mass `m' radius `R' doing pure rolling motion on a rough surface having velocity  as shown in the Figure. It makes an elastic impact with the smooth wall and moves back and starts pure rolling after some time again.
                               
  • a)
     Change in angular momentum about `O' in the entire motion equals 2mv0 R in magnitude.
  • b)
    Moment of impulse provided by wall during impact about O equals 2mv0R in magnitude
  • c)
     Final velocity of ball will be 
  • d)
     Final velocity of ball will be 
Correct answer is option 'A,B,D'. Can you explain this answer?

Consider a sphere of mass `m radius `R doing pure rolling motion on a ...
Taking angular momentum about the point PP
0−mV0R=Iω + mVR
⇒ (2/5)mR2×V0/R−mV0R=2/5mR2×V/R+mVR
⇒V=−3V0/7
