For all responses be sure to start by stating the basic equation used and to include units in your
answers.
Use the graph below to answer the following:
40
position (m)
30
20
10
2 4 6 8
t (s)
a) Describe the motion of the object modeled in the graph.
Starts at 10m, goes in positive direction at constant velocity
b) Determine the object's average velocity.
∆x
40 −10
v = = = 5
∆t
6 − 0
m
s
c) Write the mathematical equation that describes the object's motion.
x = 5 t +10
d) Determine the object's position at t = 10 s.
x = 5 t +10
x = 5(10) + 10
x = 60m
