1. Consider the data shown in Table 1 below. This data describes the position of a person walking in front of a motion detector as a function of time. That is, at each time shown, the person's distance from the motion detector is given. Plot the data points on the axes below, with position on the vertical axis and time on the horizontal axis.

According to Timothy Treadwell in 2001 "Now, the bears I live with average, the males are on average twelve hundred pounds. They're the largest bears in the world and they've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds which human on stimulants doesn't even approach. a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter statement. b. Compute the momentum of a grizzly bear using the speed you calculated in part a. and the average mass stated by Mr. Treadwell. c. How fast would a 250 lb man have to run to have the same momentum you calculated in part b? d. How fast would a 4000 lb car have to drive to have the same momentum you calculated in part b?
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.
