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.

Question 1
For these graphs,
t
1
= 3 seconds, t
2
= 9 seconds, and v
f
= -4 m/sec

2
, then what was the value of v
o
?
5 m/sec
omit
Question 2

Question #1
, if the position of
point y equals 23 meters
, then what is the value of P?
80 m
omit
Question 3
In
Question #1
, what was the object's average velocity between 3 and 9 seconds?
9.5 m/sec
omit
Question 4
For these graphs,
t
1
= 3 seconds, t
2
= 9 seconds
. In addition, the positions of y and P in meters are:
y = 23 m

v
f
= -6 m/sec
, then what is the value of v
o
?
9 x 10

70 m
omit
Question 8
For these graphs,
t
1
= 4 seconds, t
2
= 9 seconds, v
