Representations of Motion Reveiw
1.
Consider the following position vs. time graph
d
a. Determine the average velocity of the object
b. Write an equation to describe the motion of the object
2. Use the velocity vs. time graph shown below
a. Draw a corresponding position vs. time graph. Number the axes. Assume the object starts
from d = 0.
b. How far did the object travel in the interval t = 1s to t=2s?
c. Find the displacement from t=0-5s. Explain how you got your answer.
d. Find the average velocity from t = 0-5s. Explain how you got your answer.
e. Find the average speed from t = 0-5s. Explain how you got your answer.

A baseball pitcher throws a 30 m/s fastball toward the batter, 20 meters away. The batter hits a
line drive right over the pitcher's head into center field. The fielder stops the ball 2 seconds after
it is hit, 80 meters from home plate. He hesitates for 2 seconds and then throws the ball at 18 m/s
to the second baseman, who catches the ball 2.2 seconds later.
a) How long does it take for the ball to travel to home plate?
b) Find the ball's average velocity on its trip from the batter to the outfielder.
c) Find the distance from outfielder to second base.
d,e,f) Describe the motion of the baseball by sketching a position-time graph, a velocity-time
graph and a motion map.
