Max 'd' for Blocks A & B: 0.5 Friction Coefficient

[antiparticle]

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!

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

 

[antiparticle]

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.

 

[antiparticle]

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

Sorry for my english.

ah, that all makes sense now.

ok, show us what you've tried, and where you're stuck, and then we'll know how to help!
