Problem Set B

The following selection of problems are sample problems. Individual student problem sets will vary since numerical information is randomly-generated.

Directions:

For the following problems:

• Compute the unknown quantity and enter the answer in the blank.
• If an answer is negative, then place a "-" sign in front of your answer.
• do not round any computed numbers until the last calculation.
• Unless told otherwise, enter your answers accurate to the second decimal place.

Problem 1:

 Consider the position-time graph at the right. Determine the velocity (in m/s) of the object whose motion is represented by the graph. (If negative, then enter a negative answer.)

Problem 2:

 Consider the position-time graph at the right. Determine the velocity (in m/s) of the object whose motion is represented by the graph. (If negative, then enter a negative answer.)

Problem 3:

 Consider the position-time graph at the right. Determine the velocity (in m/s) of the object whose motion is represented by the graph. (If negative, then enter a negative answer.)

Problem 4:

 Consider the position-time graph at the right. Determine the velocity (in m/s) of the object at 2 seconds. (If negative, then enter a negative answer.)

Problem 5:

 Consider the position-time graph at the right. Determine the velocity (in m/s) of the object during the first 3 seconds.

Problem 6:

 Consider the position-time graph at the right. What is the net displacement (in m) of the object after 10 seconds?

Problem 7:

 Consider the position-time graph at the right. What is the total distance (in m) which the object has traveled after 10 seconds?

Problem 8:

 Consider the position-time graph at the right. Determine the distance traveled (in m) by the object after 12 seconds.

Problem 9:

 Consider the position-time graph at the right. Determine the greatest velocity (in m/s) obtained by this object (consider magnitude only in determining 'greatness').

Problem 10:

 Consider the position-time graph at the right. At what time (in seconds) does the object have the greatest displacement?

Problem 11:

 Consider the position-time graph at the right. The red line represents object A's motion and the blue line represents object B's motion. How much faster (in m/s) is the faster of the two objects moving compared to the slower object at a time of 2.9 seconds? Enter a positive number.

Problem 12:

 Consider the position-time graph at the right. Determine the average velocity (in m/s) of the object for the entire 16 seconds of motion.

Problem 13:

 Consider the position-time graph at the right. Determine the average velocity (in m/s) of the object for the first 9 seconds of motion.

Problem 14:

 Consider the position-time graphs shown at the right. The motion of seven objects is depicted on the graph. Which of the objects is/are speeding up? Enter the numbers of all that apply. If more than one apply, then string your numbers together in numerical order without spaces or punctuation marks between numbers. If none apply, then enter the number '0'.

Problem 15:

 Consider the position-time graph shown at the right. The motion of seven objects is depicted on the graph. On average, which one of the objects is moving with the greatest magnitude of velocity? Enter the number of the object.
