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.

t
1
= 5 seconds, t
2
= 10 seconds, and v
f
= -5 m/sec
.

a = 2.5 m/sec
2
, then what was the value of v
o
?
7.5 m/sec
omit
Question 2
In
Question #1
, if the position of
point y equals 26 meters
, then what is the value of P?
94.75 m
omit
Question 3
In
Question #1
, what was the object's average velocity between 5 and 10 seconds?
13.75 m/sec
omit
Question 4
For these graphs,
t
1
= 5 seconds, t
2
= 10 seconds
. In addition, the positions of y and P in meters are:
y = 26 m
and
P = 36 m
.

v
f
= -7.5 m/sec
, then what is the value of v
o
?
1.15 x 10

2
omit
Question 7
What was the object's displacement during the time interval graphed?
80.5 m
omit
Question 8
For these graphs,
t
1
= 6 seconds, t
2
= 10 seconds, v
o
= 13 m/sec
