Physics help plz?
how much force is required to keep a 780N box moving at constant velocity across the floor if the friction force between the box and the floor is 160 N?

F(net = F(applied) - F(friction)
For the box to move at constant velocity, F(net) = 0, so we get
0 = F(applied) - F(friction)
F(applied) = F(friction)
F(applied) = 160 N
