Question

The wheels fall off Beatrice's suitcase, so she ties a rope to it and drags it along the floor of the airport terminal. The rope makes a 40.0 degree
angle with the horizontal. The coefficient of kinetic friction between the suitcase and the marble floor is μk=0.12. The suitcase has a mass of 35.0kg and
Beatrice pulls on the rope with a force of 65N. (a) Draw a free body diagram of he suitcase . (b) What is the acceleration of the suitcase, while Beatrice
pulls with a 65N force at 40.0 degrees? (c) Starting from rest, for how long a time must she pull with this force until the suitcase reaches a comfortable
walking speed of 0.5 m/s?
