A particle travels along a straight-line path such that in 4 s it moves from an initial position $s_{A}=-8 \mathrm{m}$ to a position $s_{B}=+3 \mathrm{m} .$ Then in another $5 \mathrm{s}$ it moves from $s_{B}$ to $s_{C}=-6 \mathrm{m} .$ Determine the particle's average velocity and average specd during the 9 -s time interval.
A particle travelling along a straight line travels the first $50 \mathrm{~m}$ with a uniform velocity of $5 \mathrm{~m} \mathrm{~s}^{-1}$, travels at a uniform velocity of $8 \mathrm{~m} \mathrm{~s}^{-1}$ for the next $5 \mathrm{~s}$ and travels at a uniform velocity of $12 \mathrm{~m} \mathrm{~s}^{-1}$ for the next $10 \mathrm{~s}$. (i) What is the average velocity of the journey? (ii) If the last part of the journey (during last $10 \mathrm{~s}$ ), was performed at a constant acceleration of $2 \mathrm{~m} \mathrm{~s}^{-2}$ from an initial velocity of $8 \mathrm{~m} \mathrm{~s}^{-1}$, what is the average velocity of the journey?
particle travels along a straight-line path such that in 4 s it moves from an initial position SA= -8 m to a SB = +3 m. Then in another 5 s it moves from SB to sC = -6 m. Determine the particle's average velocity and the average speed during the 9-s interval
