Unformatted text preview: | v | is larger than that value for t > 3 s. (e) Yes, since v smoothly changes from negative values (consider the t = 1 result) to positive (note that as t → + ∞ , we have v → + ∞ ). One can check that v = 0 when t = 2 s. (f) No. In fact, from v = − 12 + 6 t , we know that v > 0 for t > 2 s....
