Sam is trying to move a dresser of mass m and dimensions of length L and height H by pushing it with a horizontal force F applied at a height h above the floor. The coefficient of kinetic friction between the dresser and the floor is μk and g is the magnitude of the acceleration due to gravity. The ground exerts upward normal forces of magnitudes Np and Nq at the two ends of the dresser. Note that this problem is two-dimensional.
A. If the dresser is sliding with constant velocity, find F, the magnitude of the force that Sam applies.
Express the force in terms of m, g, and μk...
