1. What is the mathematical formula for displacement, r? 2. How would you type the formula for displacement into cell E3? (Use proper formatting for entering formulas in excel) 3. What is the mathematical formula for instantaneous velocity? Average velocity? 4. How would you type the formula for instantaneous velocity into cell F3? 5. How would you type the formula for average velocity into cell H3? 6. What is the mathematical formula for instantaneous acceleration? Average acceleration? 7. How would you type the formula for instantaneous acceleration into cell G3? 8. How would you type the formula for average acceleration into cell I3? 9. Notice how the formulas for velocity and acceleration were entered into the 3rd row, not the 2nd. Why wouldn't you enter these formulas in cells F2, G2, H2, and I2?

\fIn class, you will track the amoeba's X and Y position in the image from Question 1. Then, you will create the chart below in excel. The data in columns C and D represents the X and Y positions of the amoeba measured at time t in micrometers. Use the chart below to answer Questions 2-11. You will use your answers in class to replicate this chart. A B C D E F G H t (s) X (um) Y (um) r (um) v_inst (um/s) a_inst (um/s*2) v_avg (um/s) a_avg (um/s*2) 71.91 240.05 0.00 3 71.91 226.69 W 69.51 192.79 68.83 173.96 66.78 151.36 6 65.75 134.92 7 68.83 114.72 72.60 94.85 10 9 67.12 73.28 11 10 74.65 38.35 12 11 66.78 20.55
