The position of a particle as a function of time is given by $(-5\mathrm{~m} / \mathrm{s})t+ (3 \mathrm{~m} / \mathrm{s}^2)t^2$. Plot $x$ verus $t$ for $t=0$ to $t=2\mathrm{s}$.

An expectant father paces back and forth, producing the position-versus-time graph shown in Figure 2-25 . Without performing a calculation, indicate whether the father's velocity is positive, negative, or zero on each of the following segments of the graph: B.

An expectant father paces back and forth, producing the position-versus-time graph shown in Figure 2--25. Without performing a calculation, indicate whether the father's velocity is positive, negative, or zero on each of the following segments of the graph: D. Calculate the numerical value of the father's velocity for the segments.
