Homework Statement

See question number 5.

F=m*a
W=F*s
Uniform acceleration motion equations

Actually,I am having some difficult understanding the problem.
See the F.B.D of the system,

see the friction is acting on the block in the forward direction.So how could it move to the left corner of the block?

Simple - they both move to the right but B moves faster.

Obviously I did not see your reply before I sent mine since there was less than a minute in between.

Ok... your use of italics fooled me into assuming it was a correction to my response. Apologies.
