The weight of the crate increases. d. The weight of the crate decreases. e. No Answer 2. Two ropes are supporting a slab of wood. If another weight is put on the slab in between the two ropes, which of the following is true? a. The tension on one of the ropes is thrice of the object's weight. b. The tension on one of the ropes is twice of the object's weight. C. The tension on one of the ropes is equal to the object's weight. d. The tension on one of the ropes is half of the object's weight. e. No answer 3. In the pulley problem, one of the weights has a greater mass than the other. If both of the weights are equal in mass, what would be the acceleration? a. 0 b. 9.8 m/s^2 c. 19.6 m/s*2 d. 100 m/s*2 e. No Answer 4. There are four forces acting on a pole, one points north, one points south, one points east, and the last one points west. Suppose that the initial magnitudes of these forces are all equal, at which direction you should increase the force magnitude so that the equilibrant force will point at NW? a. Increase the forces pointing the north and west. b. Increase the forces pointing the south and east. c. Increase the forces pointing the north and east. d. Increase the forces pointing the south and west. 5. A book stays at rest on an inclined plane. Which of the following forces supports the book to be at rest? a. Gravitational Force b. Incline Forces c. Static Friction d. Dynamic Friction e. No Answer6. Two horses pull horizontally on ropes attached to a stump.
