Question

Sam is trying to move a dresser of mass rn and dimensions of length L and height H by pushing it with a horizontal force F applied at a height h above the floor. (Figure 1) The coefficient of kinetic friction between the dresser and the floor is mu k and g is the magnitude of the acceleration due to gravity. The ground exerts upward normal forces of magnitudes and No at the two ends of the dresser. Note that this problem is two dimensional. 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, q, and mu k. Find the magnitude of the normal force NP. Assume that the legs are separated by a distance L. as shown in the figure. Express this normal force in terms of m, g, L, h, and mu k. Find the magnitude of the normal force Nq. Assume that the legs are separated by a distance L, as shown in the figure. Answer In terms of m, g, mu k. h. and L.

Explanation / Answer

Here is what I got when I solved it: A. F=mu_k*m*g B. Np=mm*g/2-mu_k*m*g*h/L C. Nq=m*g/2+mu_k*m*g*h/L Hope this helped!
