Uniformly Accelerated Particle Model:
Free Fall on Planet Newtonia
The stroboscopic photograph on the back of this page shows a ball falling freely past a window
on planet "Newtonia." Using any data you might obtain from the photo and your knowledge of
free fall, solve each of the following problems. You may use a ruler and calculator. Show your
work and/or explain your reasoning in the blank space below each question.
1. What is the average velocity of the ball between points A and E7
2. What is the average velocity of the ball between points A and C?
3. What is the instantaneous velocity of the ball at point B7 Explain your reasoning!
4. What is the average velocity of the ball between points C and E?
5. What is the instantaneous velocity of the ball at point D? Explain your reasoning!
6. How much time is elapsed between the time that the ball was at point B and the time that the ball
was at point D?
7. What is the acceleration due to gravity on the planet Newtonia?
8. From how high above point A was the ball released?
