A man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runner's time at the end of each lap, obtaining the data in the following table. Time (s) Distance (m) 31 200 63 400 96 600 139 800 183 1000 235 1200 291 1400 351 1600 (a) What was the man's average speed (rate) between 63 s and 139 s? (Round your answer to two decimal places.) m/s (b) What was the man's average speed between 235 s and 351 s? (Round your answer to two decimal places.) m/s (c) Calculate the man's speed for each lap. Is he slowing down, speeding up, or neither? slowing downspeeding up

What is the speed of a car going v=1.000 mph in SI units? Notice that you will need to change miles to meters and from hours to seconds. you can do each conversion separately. Use the facts that 1 mile=1609 m and 1 hour= 3600s
Averages follow the same rule. Suppose a car travels around a track three times. Your measurements for the three trials are 45.0 km/h, 48.21 km/h, and 47.024 km/h. Determine the average speed of the car. 45.0 + 48.21 + 47.024 = 140.234 140.234 + 3 = 46.744 66 Because the least precise measurement is 45.0 km/h, the answer can be precise only to the nearest one-tenth. Thus the correct answer, rounded off, is 46.7 km/h. Answer the following questions. 15.

Using Excel to make a plot of the Position vs Time given in the following table. The dependent variable is the position (y-axis) and the independent variable is the time (x-axis). This is the measured position of a rock as it falls from the top of a very high cliff and obeys the equations y = 1/2gt2. Make sure you label the plot properly. Label the plot and the plot axes with the appropriate labels.
