position vs time for three cars\nuse the drop - down menus to complete each sentence.\n is moving the fastest.\n is standing still.\n started at the same location.

Answer

Explanation:

Step1: Recall speed - slope relationship

Speed is given by the slope of the position - time graph. The steeper the slope, the greater the speed.

Step2: Analyze slopes of A, B and C

Line A has a steeper slope than line B. Line C has a slope of 0.

Step3: Determine the fastest - moving car

Since A has the steepest slope, car A is moving the fastest.

Step4: Determine the stationary car

Since C has a slope of 0 (horizontal line), car C is standing still.

Step5: Check starting positions

Lines A and B start from the origin (0,0), so cars A and B started at the same location.

Answer:

  1. A
  2. C
  3. A and B
