Here is a graph of an object's motion. Which sentence is a correct interpretation?

• The object is moving at a constant velocity. Then it slows down and stops.
• The object doesn't move at first. Then it rolls forward down a hill and finally stops.
• The object doesn't move at first. Then it moves backwards and then finally stops.
• The object rolls along a flat surface. Then it rolls forward down a hill, and then finally stops.

Consider the following graphs, noting the different axes. Which of these represent(s) motion at constant velocity?

• I, II, and IV
• I and III
• II and V
• IV only

The following represents the velocity-time graph for two objects, A and B. Which of the following statements is true?

• At t = 4 s, both objects have covered the same distance.
• Object A is motionless.
