2) The velocity function is v(t) = t - 6t + 8 for a particle moving along a line. The graph of the velocity function is given. 25 a. Estimate the displacement (net distance covered) of the particle during the time interval [-2,5]. 20 Explain your process used for estimating the displacement. 15 b. Estimate the total distance traveled by the particle during the time interval [-2,5] Explain your process used for estimating the total distance. 10 5 10 15
