Beatrice needs to drag her suitcase again. This time she pulls with a force of 105 N

Question:

Beatrice needs to drag her suitcase again. This time she pulls with a force of 105 N at 38.0° with the horizontal. The coefficients of static and kinetic friction between the suitcase and the floor are 0.273 and 0.117, respectively. 

(a) Draw an FBD of the suitcase. 

(b) What is the magnitude of the normal force acting on the suitcase due to the floor? 

(c) Does the suitcase slide, or does she need to increase her force? 

(d) If the suitcase slides, what is its acceleration? If it does not slide, to what magnitude should she increase her force?
