Unit 1: One-Dimensional Kinematics

Problem Set B


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.)


The slope of a position-time graph is equal to the velocity of the object. This problem involves a straight-forward calculation of the slope. If you are having difficulty with this problem, then you will likely find mnay of the problems in Set B to be difficult. You should first take some time to read about slope calculations online at The Physics Classroom.



If you are still having difficulty with this particular problem, then it might be that you are failing to enter your answer with the proper sign. A slope value is positive for a line which slopes upward and negative for a line which slopes downward.
