PhysicsLAB Practice Problems
Kinematics Functions

Topics: On this worksheet you will work with position, velocity, and acceleration functions expressed in terms of time.

Page Directions The numerical values in this worksheet are randomly generated allowing students the opportunity to conveniently practice, and drill, common situations.

Before beginning any given worksheet, please look over all of the questions and make sure that there are no duplicate answers shown for the same question. If duplicates are present simply refresh the page until every answer is unique.

In order to check an answer (even when you are just starting the worksheet on Question 1) it is necessary to omit any questions that you have not answered. Once you start submitting answers, the page may be checked as many times as necesasary without changing the randomized answers. Relevant scoring will be provided at the top of the page only when you answer all of the questions on your original submission.


Question 1  Given that a cart obeys the position function s(t) = 5t2 - 4t + 10. What would be its instantaneous position at t = 4 seconds?
Question 2  What is the cart's displacement between t = 4 seconds and t = 9 seconds?
Question 3  What is the cart's average velocity during the interval t = 4 seconds and t = 9 seconds?
Question 4  What is the cart's change in velocity during the interval t = 4 seconds and t = 9 seconds?
Question 5  What would be its instantaneous acceleration at 9 seconds?
Question 6  True or False. The acceleration in Question 5 was constant between between t = 4 seconds and t = 9 seconds?
