3) A toy car drives along a long strait track. The car starts from the eight-meter mark and travels
Stu
backward, arriving at the two-meter mark at second three. The car then slows and stops at the
one-meter mark at second four. The car stays stopped for two seconds and then moves forward
at 1.5 m/s for the remainder of the ten-second period. Draw correct Position vs. Time and
Velocity vs. Time graphs to represent this motion. (10 points)

4. Student Dialog homework
Here is a dialog among two students discussing the motion diagram below.
Student 1: The velocity vs. time graph is drawn wrong.
Student 2: What is wrong with it? I don’t see anything wrong.
Student 1: Well, for one thing, from second 0 to 3 the car should be increasing in speed,
and the velocity graph shows it standing still.
Student 2: I think it is correct, from second 0 to 3 the position graph shows a constant
speed, which is what the velocity graph shows
