A particle moves along a line. Its position, s in metres, at t seconds is given by: s(t) = (t- 4t + 3) a) Determine the initial position of the particle. b) What is the velocity at 6 seconds? c) Determine the total distance traveled during the first 6 seconds. d) At t = 6 is the particle moving to the left or to the right? Explain how you know.
