Science Assessment

An object is moving at a speed of 10 meters per second (m/s). A force begins to act on the object at exactly 9 o’clock in the morning (9:00 am) and continues to act until 9:06 am. The force is pushing the object forward. The strength and direction of the force stay the same the entire time. The force that is pushing the object forward is always greater than any forces slowing the object down.

Which table (A, B, C, or D) shows what the object's speed might be each minute?  Assume that if a change in speed has occurred, the change is shown in the table.
