A box of mass 1kg is placed on a table and is connected to a hanging mass m by a string strung over a pulley. If the coefficient of kinetic friction between the box and the table is .3 and the box slides at a constant speed of .5m/s what is the weight of the hanging mass?

to find the weight of the hanging mass:

F_g=mu*mg
=.3*m*9.8
=2.94N

b) what is the tension in the string?
F_f=mu * FN
=.3*9.8
=2.94

T-F_f=ma
T-2.94= 1kg(a)
what is the accleration is it zero?
so would that mean
tension equals 2.94N (the same as the frictional force?
