The speed of a particle in a test laboratory was noted every second for 3 seconds. The results are shown in the following table. Use the left endpoints and then the right endpoints to estimate the total distance the particle moved in the first three seconds. t (sec) 2 3 v (ft/sec) 9 7.5 6.5 The estimate of the total distance the particle moved in the first three seconds using left endpoints is |ft. The estimate of the total distance the particle moved in the first three seconds using right endpoints is |ft
