Hi all,

Would some one please take a look at this problem for me? I am trying to work out this problem, but I have some trouble...

The coefficient of kinetic friction between the dresses and the floor is μk. The ground exerts upward normal forces of magnitudes Np and Nq at the ends of the dresser.

a) If the dresser is sliding with constant velocity, find the magnitude of the force F.

b) Find the magnitude of the normal force Np

c) the magnitude of the normal force Nq.

I have tried to work our part of the problem, but I am not sure.

summation Fy = nq - w = 0 so Nq = w

summation Fx = F - f = 0 so F =f

F = μkw so F = μk(mg)

not sure if this is correct, the magnitude of F is

F = μk(mg)

Please help,
