4. A particle moves along the x-axis in such a way that its position at time t for t 2 0 is given by s(t) = =t' - 312 +8t. A. Find the position of the particle at time t = 3. (1 point) B. Show that at time t = 0, the particle is moving to the right. (2 points) C. Find all values of t for which the particle is moving to the left. (2 points) D. What is the total distance the particle travels from t = 0 to t = 4? (4 points)
