1. You are watching (and recording) a jet ski race. A racer speeds up from rest to 70 mph in just a few seconds, then continues at a constant speed. Draw a basic motion diagram of the jet ski, using images from the recording, from 10 s before reaching top speed until 10 s afterward. 2 . 3. The figure below shows the motion diagram of a drag racer. The camera took one frame every 2 s. 1 frame every 2 s x (m) 200 400 600 800 a. Measure the x-value of the racer at each dot. List your data in a table showing each position and the time at which it occurred. b. Make a position versus time graph for the drag racer. You only have data for certain Instants, so the graph should consist of dots that are not connected together. x (mij 120 4. Write a short description of the motion of a real object for which 80 the figure to the left would be a realistic position versus time graph. 40 2 404 7. Write a short description of a real object for which the figure to 30 the left would be a realistic position versus time graph. 20 20 30 Alan leaves Los Angeles at 8:00 A.M. to drive to San Francisco 400 ml away. He manages to travel at a steady 50 mph in spite of traffic. Beth leaves Los Angeles at 9:00 A.M. and surprisingly manages to also drive at a constant speed, in this case 60 mph. Who gets to San Francisco first? (Beth) b. How long does the first to arrive have to wait for the second? (20 minutes)
