(a) From Figure 2.6, how many seconds did it take me to go from \(x=+1.0 \mathrm{~m}\) to \(x=+4.0 \mathrm{~m}\) ?

(b) From \(x=+2.0 \mathrm{~m}\) to \(x=+3.0 \mathrm{~m}\) ?

(c) At what instant did I reach \(x=+2.5 \mathrm{~m}\) ?

(d) For how long was I at \(x=+2.5 \mathrm{~m}\) ?

Figure 2.6 By interpolating the data points in Figure 2.3, we obtain a smooth curve representing my motion. x (m) 5p 4 3 2 1 0 0 2 3 4 t(s) 5 6 7
