You will use Excel or similar software and the eq. 1 to complete this assignment. You will write the report using the format that is described in this manual. Analysis To analyze the eq. 1, you will first set up the problem. For initial position, use the following: =RAND()*100. For initial velocity: =RAND()*20. For the acceleration:=RAND()*5. And for error bars: =(0.4+RAND())*200. Set up the time column. You can start at 0 or any other value, the increment should be at least 2 seconds, and create at least 50 points. (Hint - don't just type all numbers manually!). Enter the eq. 1 into the column called position or distance (remember units for each!! Remember static cells with $$). Make the scatter plot - no connecting lines etc., only dots. Set the error bars to the value in 'error bars'. Add trendline (what type should it be and why?). Show the fit equation. Do the fit parameters correspond to the ones that you set initially? Remember to label the axis! All helpful hints are in the video that is provided. Other resources also exist!

(c) How long does the acceleration take? To solve this part, first identify the unknown, then discuss how you chose the appropriate equation to solve for it. After choosing the equation show your steps in solving fir the unknown, checking your units. (d) Is the answer reasonable when compared with the time for a heartbeat?

A dolphin in an aquatic show jumps straight up out of the water at a velocity of 13.0 m/s. (a) List the knowns in this problem. (b) How high does his body rise above the water? To solve this part, first note that the final velocity is now a known and identify its value. Then identity the unknown, and discuss how you chose the appropriate equation to solve for it. After choosing the equation, show your steps in solving for the unknown, checking units, and discuss whether the answer is reasonable. (c) How long is the dolphin in the air? Neglect any effects due to his size or orientation.
