The car starts at point A, descends the hill, speeding up as it travels from A to B; after a short straight section of track, the car rounds the curve and finishes at point C. The car continuously slows down from point B to point C. Use this information to complete the table below Point Direction of Velocity Vector Direction of Acceleration Vector Free Fall Motion 20. Define free fall motion? 21. Can this type of motion be observed on Earth? If not, why not? 22. Two objects are dropped from the same height at the same time and experience free fall motion. Describe what you would observe 23. A rock is dropped from a rest position at the top of a cliff and free falls to the valley ng negligible air resistance, use kinematic equations to determine the stance fallen and the instantaneous speeds after each second for 5 seconds a. At which of the listed times is the acceleration the greatest? Explain your answer b. At which of the listed times is the speed the greatest? Explain your answer 24. If the falling time of a free-falling object is doubled, the distance fallen increases by a factor of fallen values to support your answer Identify two times from the previous question and use the distance Page 6 of 7 1821 words English (United States) 画Focus圜昂 2 2
