1. A 2.0-m rope is lying on a table. You pick up one end and start raising it. How high above the table is the center of mass of the rope when half the rope has lifted off the table?

2 a rope is lying on a table. You pick up one end and start raising it with a constant velocity. The force you have to exert on the rope is? A. Equal weight of proportion of the rope that is not on the table b. greater than the weight of proportion of the rope that is not on the tale c. Less than the weight of proportion of the rope that is not on the table but not zero N D. Zero N

3. A rope is held from one end in such a way that the lower end just touches a table. The rope is then lowered onto the table with a constant velocity. The force that is needed to hold the upper end of the rope is? A. Equal to the weight of proportion of the rope that is not in the table. b. greater than the weight of the proportion of the rope that is not on the table C. Less than the weight of proportion of the rope that is not on the table but not zero N D. Zero N
