Chapter 12, Problem 12-16(choose chapter or problem)
A particle travels along a straight line such that in 2 s it moves from an initial position \(s_{A}=+0.5 \mathrm{\ m}\) to a position \(s_{B}=-1.5 \mathrm{\ m}\). Then in another 4 s it moves from \(s_{B}\) to \(s_C=+2.5\mathrm{\ m}\). Determine the particle's average velocity and average speed during the 6-s time interval.
