the coefficient of friction between block A and the horizontal surface is 0.43. What must be the weight of the hanging block B if this block is to descend at constant speed once it has been set into motion? Mass of block A is 5.0 kg

I assume block b is attached to A, ..
net force=total mass* a, but it is at constant speed, so
Mb*g-mu*Ma*g=0
solve for Mb*g (weight of block B)
net force=total mass* a, but it is at constant speed, so
Mb*g-mu*Ma*g=0
solve for Mb*g (weight of block B)
