Homework Statement



A block A has mass =2kg and is attached to a spring of spring constant=40N/m .Another block of mass 4kg is pressed against A so that the spring is compresses by a distance 'd' .Then find the maximum value of 'd' for which on release of the B does not lose contact from the wall {friction coefficienT between the floor and the block=0.5].The block A is kept adjacent to the wall.

Hi antiparticle! :smile:

I don't get it :redface: … if A is against the wall, where are the spring and B? :confused:

On the left side of block A there is a wall on the right side of A there is a spring attached to A and the other end of the spring is attached to B.Now B is pushed against the wall so that the spring compresses.
I think now it is more clear.

Just one thing still confusing me …

"Then find the maximum value of 'd' for which on release of the B does not lose contact from the wall "

… but B isn't in contact with the wall. :confused:

I meant that A should not leave contact with the wall.

Sorry for my english.
