Post your question related to above video lecture
why work done by spring with elongation y is taken negative and it is in the direction of motion of block B

Post your answer here
sir why did you take work done on friction as Mmg(x+y)
8 years ago by saikiran
Ans 1 ->
Its force of the friction is mumg and we applied W/EE theorem between initial compression point and final extension that is x+yy.now multiplying both force and distance u will get ur answer.OK
