A hard rubber ball is dropped from rest. It falls to the concrete floor and bounces back up ALMOST to its initial height. A motion detector is mounted on the ceiling directly above the ball‚ facing down. So‚ the positive direction -- the away-from-the-detector direction -- is downward. Draw the position‚ velocity‚ and acceleration graphs. Since moving downward is a positive direction‚ is the velocity positive when the ball falls‚ 0 when it hits the ground‚ and then negative when it moves up?

Recently I decided to observe how the inflation of a soccer ball influences the accuracy of a soccer ball. In this experiment‚ I used one Nike soccer ball‚ one pair of Adidas soccer cleats‚ a soccer field‚ an air pump and a pressure gauge. I used a soccer ball with the PSI of 8.7‚ a soccer ball with 9.5 PSI‚ and a soccer ball with 7.75 PSI. Changing the PSI of the soccer ball changes the results because the PSI changes the hardness of a ball. I can see how the PSI affects my accuracy by recording the
