All About Quest
Quest is an online bank of science and math questions managed by the College of Natural Sciences. To get an account on Quest email your EID to Patsy McDonald at [email protected].
Main points of Quest
- http://quest.cns.utexas.edu is the starting point for you and your students.
- Students download a pdf of the questions and enter answers online.
- You must “Publish to Class” to make the assignment available to students.
- Choosing a textbook does not give you problems from that book it simply lists problems by topic with order of the topics matching the order of topics in that book.
- Questions for which students enter a numerical answer have a tolerance of +/- 1%.
- Many numerical questions give random numbers so each student gets different numbers.
- You can choose to allow students multiple attempts or only a single attempt. For multiple attempts each wrong answer gives the student negative points. Details of the grading algorithm are available in the Help section.
- You can choose to allow late submissions with various stipulations.
- You can submit your own questions by typing the question in LaTeX and emailing it to Patsy McDonald.
- You can import assignments you’ve made for other classes whether they are current classes or from previous semesters.
- If you find a problem with an error you can flag it from your assignment page. You can also email corrections to Patsy.
- You can enter addition comments to accompany any problem
- You can print questions for a scantron exam or students can enter exam answers using a Clicker.
Pros of Quest
- You do not have to spend time writing questions for homework or exams.
- Quest does the grading for you.
- You see the success rate for each question and a histogram of the number of attempts for each question. In Manage Students you can look at an individual student’s questions and answers.
- Students like the instant feedback of knowing if their answer was right or wrong.
Cons of Quest
- You have to spend time looking for questions. There is no way to sort questions other than by textbook.
- There is no easy way to see what the most common incorrect answer was for any question.

- 2717 Answer in units of kg · m/s.
002 10 points The linear impulse delivered by the hit of a boxer is 98 N · s during the 0 s of contact. What is the magnitude of the average force exerted on the glove by the other boxer?
- Answer in units of N.
003 10 points A child bounces a 55 g superball on the side- walk. The velocity change of the superball is from 23 m/s downward to 14 m/s upward. If the contact time with the sidewalk is
1 800 s, what is the magnitude of the average force exerted on the superball by the sidewalk?
1628 Answer in units of N.
004 10 points An open train car moves with speed 18 m/s on a flat frictionless railroad track, with no engine pulling the car. It begins to rain. The rain falls straight down and begins to fill the train car. The speed of the car
stays the same.
005 10 points What is the momentum of a two-particle sys- tem composed of a 1000 kg car moving east at 60 m/s and a second 1500 kg car moving west at 15 m/s? Let east be the positive direction.

9 g object overtakes and collides with the 6 g object. Immediately after the collision, the y-component of the velocity of the 9 g object is 4 m/s upward.
What is the y-component of the velocity !v of the 6 g object immediately after the collision?
!vy = 2 m/s downward
!vy = 4 m/s downward
!vy = 4 m/s upward
!vy = 6 m/s downward
!vy = 2 m/s upward
!vy = 6 m/s upward
017 (part 1 of 2) 10 points Assume: The bullet penetrates into the block and stops due to its friction with the block. The compound system of the block plus the bullet rises to a height of 0 m along a circular arc with a 0 m radius. Assume: The entire track is frictionless. A bullet with a m 1 = 30 g mass is fired horizontally into a block of wood with m 2 = 4 .04 kg mass. The acceleration of gravity is 9 m/s 2.

Calculate the total energy of the composite system at any time after the collision.
018 (part 2 of 2) 10 points Taking the same parameter values as those in Part 1, determine the initial velocity of the bullet.
- Answer in units of m/s.
019 (part 1 of 2) 10 points A 478 kg mass is sliding on a horizontal fric- tionless surface with a speed of 11 m/s when it collides with a 90 kg mass initially at rest, as shown. The masses stick together and slide up a frictionless track at 60◦ from horizontal.
