A mass of 8.0 kg lies at rest on a horizontal surface with a coefficient of kinetic friction of 0.60 and a coefficient of static friction of 1.50. Then, a force of 20 Newtons is applied in the +x direction, a force of 40 Newtons is applied in the -y direction, and another force is applied in the +y direction. For the unknown force in the +y direction, what is the minimum force it needs to be such that the mass begins to move?
