PhysicsLAB Practice Problems
Kinematics Functions

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

Question 1  Given that a cart obeys the position function s(t) = 8t2 - 2t + 11. What would be its instantaneous position at t = 2 seconds?
Question 2  What is the cart's displacement between t = 2 seconds and t = 10 seconds?
Question 3  What is the cart's average velocity during the interval t = 2 seconds and t = 10 seconds?
Question 4  What is the cart's change in velocity during the interval t = 2 seconds and t = 10 seconds?
Question 5  What would be its instantaneous acceleration at 10 seconds?
Question 6  True or False. The acceleration in Question 5 was constant between between t = 2 seconds and t = 10 seconds?
