  1. 1The drawing shows the motion diagram of a car that has been photographed at equal time intervals. The dot represents the position of the front of the car.
    The description that could describe the motion of the car is:

    Imagen de la pregunta 1
    1. AThe car is moving to the left, first speeding up and then slowing down.
    2. BThe car is moving to the right, first speeding up and then slowing down.
    3. CThe car is moving to the right and slowing down.
    4. DThe car is moving to the right and speeding up.
  2. 2The drawing shows the motion of a car that has been photographed at equal time intervals. Assume that the car is moving toward the right.
    The Position versus Time graph that could match the motion of the car is:    Imagen de la pregunta 2
    1. AImagen de la opción A
    2. BImagen de la opción B
    3. CImagen de la opción C
    4. DImagen de la opción D
  3. 3The Position versus Time graph of a car is shown on the left.

    What is the average velocity of the car between 2.5 s and 7.5 s?    Imagen de la pregunta 3
    1. AA 1.0 m/s
    2. BB 2.0 m/s
    3. CC 3.0 m/s
    4. DD 4.0 m/s
  4. 4The Position versus Time graph of a car is shown on the left.

    What do you need to do to determine the instantaneous velocity of the car at 5 s?
    1. AA Draw a tangent line at 5 s and calculate the slope of the line.
    2. BB Draw a secant line between 0 seconds and 10 seconds and calculate the slope of the line.
    3. CC Draw a secant line between 0 seconds and 10 seconds, calculate the slope and divide it by 2.
    4. DD Read the position value that corresponds to 5 s and divide it by 5.
  5. 5The graph on the left describes the motion of a car.

    Which of the following are correct verbal descriptions of the car's motion? Select two choices.    Imagen de la pregunta 5
    1. AThe car is definitely moving to the right.
    2. BThe car is definitely moving in the positive x-direction.
    3. CThe car is definitely slowing down.
    4. DThe car is definitely speeding up.
  6. 6It is observed that a car traveling toward the south on a straight highway is slowing down.

    Which of the following statements must be true? There are two correct statements.
    1. AThe velocity and speed are both positive
    2. BThe velocity vector is directed south
    3. CThe acceleration vector is directed south
    4. DThe acceleration vector is directed north
