A person pulls a 26 kg suitcase using a rope attached to the suitcase at an angle of 28 degrees to the horizontal. The coefficient of static friction of the suitcase with the floor is 0.3 and the coefficient of kinetic friction is 0.2.
a. Draw a sketch of the situation and a force diagram of the suitcase, labelling all forces clearly.
b. With what force does the woman have to pull to start the suitcase moving from rest?
c. If she continues to pull with this force after the suitcase is moving, what will be the suitcase's acceleration?
d. How long will she have to pull the suitcase with this force until the suitcase is moving at 2m/s?
