Suppose you wanted to find the acceleration of a ball falling to the ground. Which step in the following measurement procedure needs to be re-worked? 1) To measure the time

it took the ball to fall one meter. We used a stopwatch with a resolution of 0.01{s} 2) We decided to measure the time it took to fall 15 times at each height:0.2[m], 0.4[m], 0.6[m], 0.8[m], 1.0[m]. 3) To analyze the data, we decided to make a plot. 4) To compare our measurement to an accepted value. We made a whisker plot with the accepted value and the measured value. The measured value has uncertainty bars found by using the min/max method.
