Unit 1 Quiz#2

Interpretting Graphs:

Consider the velocity vs. time graph below for questions #1-5. The motion of five different people (A, B, C, D, and E) are shown on the graph. Study the graph and answer the following questions. Some questions may have more than or less than one answer. Place your answers in the blank.

  1. Which person(s) changes direction during the time of motion?
  2. Which person(s) is/are not moving?
  3. Which person(s) is moving with more than one speed during the course of its motion?
  4. Which person(s) has/have a constant, negative acceleration value?
  5. On average, which person has the greatest magnitude of acceleration?

8. Renatta Oyle is driving rightward (+ direction) at 30 m/s when she suddenly slows down at a constant rate of acceleration to a rest position in 5 seconds.

  1. Identify the direction of the acceleration of the car. ________________ Explain.

     

  2. Construct a motion diagram (i.e., an "oil drop diagram") of the car's motion during this braking period.
  3. Sketch plots of position vs. time and velocity vs. time for the car's motion during this braking period. If a plot should be a straight line, make it clearly straight; if it should be curved, make it clearly curved; etc.
  4. Use your velocity-time plot to determine the displacement of the car during the 5 second braking period. Circle your answer. PSYW

9. Rex Things throws his mother's glass vase straight upward into the air with a velocity of 20 m/s, upward. The velocity-time plot is shown at the right.

  1. The vase travels upwards, reaches its peak and then falls back downwards. At what time does the vase reach the peak of its trajectory? t = ___________ s

     

  2. As the vase is moving upwards, it is slowing down. Therefore, its acceleration is _______________ (up or down).

     

  3. As the vase is moving downwards, it is speeding up. Therefore, its acceleration is _______________ (up or down).

     

  4. Use the velocity-time plot to determine the acceleration of the vase. PSYW
