Practice Problems
Uniform Acceleration: SVA Graphs
Directions:
On this worksheet you will have an opportunity to practice the relationships between families of position-time, velocity-time, and acceleration-time graphs. Please note that the diagrams are not drawn to scale.

omit
Question 4
For these graphs,
t
_{1}
= 4 seconds, t
_{2}
