Answer 1

The blocks m1 and m2 will move with combined acceleration a:

From F.B.D. of block m1

T−f1=m1a...(i)

as the block m1 is sliding, kinetic friction will be acting:

T−μkN=m1a...(ii)

N=mg...(iii)

From F.B.D. of block m2

m2g−T=m2a...(iv)

adding (ii) and (iv)

a=m1+m2m2g−μkN...(v)

T=m2g−m2a=m2(g−m1+m2m2g−μkN)

=m2(m1+m2m1g+μkm
