1. What is the average Velocity between Points (0, 0) and Point C? 2. What is the instantaneous velocity of Point A? Calculate this by calculating the slope of the line (rise/run) from the 2 nearest points – not using Point A. 3. Describe in words the motion of the spider monkey from Point A to Point C. 4. What is the instantaneous velocity of Point C? To do this, draw a tangent line at Point C so that it just skims Point C and is perpendicular to the line at that point. Then calculate the slope of that Tangent line that is passing through Point C. 5. Describe in words the motion of the spider monkey from Point C to Point D. 6. What is the instantaneous velocity of Point D? 7. What is the instantaneous velocity of Point G? 8. Do you see a pattern of the velocity at the Peaks and Valley’s of the Graph? What is it? 9. Describe in words what happens to the spider monkey’s motion as he reaches Points C, F, I. 10. Describe in words what happens to the spider monkey’s motion as he reaches Points D and G. 11. What happens to the instantaneous velocity of the Spider Monkey as he changes direction? 12. When traveling in one dimension (straight line, forward and backward) is it possible to change directions without stopping? 13. Now refer to Graph 3 that you created for the “Graphing Position vs. Time” Assignment. Figure out the Instantaneous velocity of Point R.
