1. The problem statement, all variables and given/known data Using the data found, in this chart, create a time-velocity data table. Time(s),Position(m)[down]: (0,0), (0.25,0.29), (0.50,1.15) 2. Relevant equations v= change in position/change in time 3. The attempt at a solution I'm just wondering which sets of data points I should be using to calculate the velocity at 0.25 seconds: for example v=(0.25-0)/(0.29-0) is different from v=(0.50-0.25)/(1.15-0.29).
