hey easy one!!

To overcome frictional force and to move the block up,

mgcos37=Mg

M= 3m/5

if u dint understand i'll xplain

edit: the normal force N acting on small block is mgcos37

frictional force acting downward is N = mgcos37 = 3mg/5

The spring has nothing to do!!!

The tension acting upwards is T = Mg

T >  N .For the minimal case, T =N

that implies 3mg/5=Mg

M= 3m/5
