A basketball player starts at the left end of the court and moves in a straight line
toward right. His velocity graph is shown below. Answer the following:
a) During 0-12 s, At what time or times does the player reaches
the maximum speed? What is the player’s maximum speed?
b) At what time or times does the player change direction, if any?
c) What is the player’s acceleration during the first 6.0 seconds? During 6.0 -12
seconds? Does the player have larger acceleration during the first 6.0 seconds of motion,
or last 6.0 second of motion? (show your work)
what would the motion look like for a person starting some distance away from the origin and walking at constant speed to the right?
Draw a graph of position vs. time for a person starting 0.4 to the right of the origin and walking at constant speed to the right. Please include explanation of your predictions.
