Use the data table of displacement time data to get a line of best fit using your Ti-83 calculator. Once you have the equation, graph it so that you can answer the questions 1-5 that follow. Assume that the data below is for an object that is launched vertically upwards.
Time (sec) Displacment (m)
Using the information above, calculate the average speed for the object from 0.75 sec to 2.9 sec.
I've tried using the distance divided by time, but that hasn't worked, so I think the equation is actually where my problem is. The one I've tried mainly is average speed=change in distance/change in time
