I am posting a new type of ques here and its a multimechanical ques as it contains all the concepts of mechs viz, Kinematics,NLM,momentum,Collision,rotation.

 

In the figure, the 2 balls are are rolling without slipping. They undergo a perfectly inelastic collision at t=0. Find the time t taken by the total mass to stop after collision.

Given-Coefficient of friction= .

 

Find the answer in terms of the given variable viz, M1,M2,R1,R2,V1,V2,.

 

Yeh ques kar liya, samjho mechanics finish.
