Kinesiology [Note that you will need to label 0 on the vertical axis for the graphs you sketch. Assume away from the origin is positive and all positions are positive.] Sketch the corresponding graphs for each description • Smooth out the graphs. • There are right and wrong answers to these. I am looking for the correct one, and not necessarily what you found through moving in front of the sensor. Position vs. Time Velocity vs. Time Acceleration vs. Time 1. The object moves with a steady (constant) velocity toward the origin for 5 seconds and then stands still for 5 seconds. Position (m) Velocity (m/s) Acceleration (m/s) Time (8) Time (s) Time (s) Position vs. Time Velocity vs. Time Acceleration vs. Time Position (m) Velocity (m/s) TTTTTTTTTT Acceleration (m/s) IIIII 0 + 0 TTTTTTTTT Time (s) 0 Time (s) Time (s) 2. The object moves with a steady velocity away from the origin for 5 seconds, then reverses direction and moves at the same speed toward the origin for 5 seconds. 3. The object moves away from the origin, starting slowly and speeding up.

Sketch the corresponding two other graphs and answer the question within a a few sentences in the space below the graphs. Position vs. Time Velocity vs. Time Acceleration vs. Time 4.
