track designed for a physics lab. 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

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

- (Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) . The following are speeds and headings displayed on a GPS receiver, (Heading gives the direction of motion based on north = 0°, east = 90°, south = 180°, etc,) In each case, indicate whether the receiver was accelerating during the time between the displays and, if it was, describe in what way the receiver was accelerating. (a) Initially: 60 mpht 70°; 5 seconds later: .50 mph, 70°. (b) Initially: .50 mph, 70°; 5 seconds later: 70 mph, 70°. (c) Initially: 60 mph, 70°; 5 seconds later: 60 mph, 90°.arrow_forwardKinematics graphs are great for showing how a quantity depends on time. For example, an acceleration-versus-time graph shows how acceleration depends on time. a. Based on your experience with two other kinematics graphs (position- and velocity-versus-time), describe how to plot an acceleration-versus-time graph. b. Describe how all three kinematics graphs are connected by slopes of tangent lines (derivatives). c. If a particles acceleration is positive and constant, what is the shape of the curve in each of the three kinematics graphs?arrow_forward(Indicates a review question, which means it requires only a basic understanding of the material to answer.

Scenes in films or television programs sometimes show people jumping off moving trains and having unpleasant encounters with the ground. If someone is on a moving flatbed train car and wishes to jump off, how could the person use the concept of relative speed to make a safer dismount?arrow_forward
- (Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) . As a car goes around a curve, the driver increases its speed. This means the car has two accelerations. What are the directions of these two accelerations?arrow_forwardA trapper walks a 5.0-km straigt4ine distance from his cabin to the lake, as shown in the following figure. Use a graphical method (the parallelogram rule) to determine the trapper’s displacement directly to the east and displacement directly to the north that sum up to his resultant displacement vector. If the trapper walked only in directions east and north, zigzagging his way to the lake, how many kilometers would he have to walk to get to the lake?arrow_forwardAn adventurous dog strays from home, runs three blocks east, two blocks north, one block east, two block north, and two blocks west. Assuming that each block is about 100 m, how far from home and in what direction is the dog? Use a graphical method.arrow_forward

During 200-meter and 400-meter races, runners must stay in lanes as they go around a curved part of the track. If runners in two different lanes have exactly the same speed, will they also have exactly the same centripetal acceleration as they go around a curve?
