record the bug’s position in ﬁvesecond intervals. After the bug
crawled off the meter stick, Peter created the table shown. What is the displacement of the bug between t = 0.00 s and t = 20.0 s?
(a) +393 cm (c) +65.7 cm
(b) —39.9 cm (d) —16.1 cm What is the total distance that the bug traveled between t = 0.00 s‘and t = 20.0 5? Assume the bug only (c) 16.1 cm
