Question

A pair of students are lifting a heavy trunk on move-in day (Figure 1) . Using two ropes tied to a small ring at the center of the top of the trunk, they pull the trunk straight up at a constant velocity v_vec. Each rope makes an angle theta with respect to the vertical. The magnitude of the weight of the trunk is w.

Which of the following statements are correct?

1.The x component of the weight of the trunk is zero.
2.The y component of the weight of the trunk is zero.
3.The x components of the forces of tension in the ropes have the same magnitude and sign.
4.The x components of the forces of tension in the ropes have the same magnitude and opposite sign.
5.The y components of the forces of tension in the ropes have the same magnitude and sign.
6.The y components of the forces of tension in the ropes have the same magnitude and opposite sign.
7.The x component of the acceleration of the trunk is zero.
8.The y component of the acceleration of the trunk is zero.
9.The angle between the ropes is theta.
10.The angle between the ropes is 2theta.
