A particle moves along a straight line with equation of motions =13 - 2t. Find the smallest value of its velocity (for t ≥ 0)

Answer 1

s(t) = 13 -2t

take the derivative

s'(t) = v(t) = -2 = velocity at all times t

lowest value of velocity is -2 as velocity is always -2

maybe the problem was different when originally written? the solution, as written, looks suspiciously odd.
