For each speed in Figure 2.9, what are

(a) the distance traveled between \(t=0\) and \(t=1.50 \mathrm{~s}\) and \((b)\) the ratio of the distance traveled to the corresponding time interval? For each speed, what are

(c) the time interval required to move from \(x=2.00 \mathrm{~m}\) to \(x=3.50 \mathrm{~m}\) and \((d)\) the ratio of the distance traveled to the corresponding time interval?

Figure 2.9 Forward motion at two speeds. Walking half as fast means taking twice as long to travel the same distance. To get to the arbitrary point x = 3.5 m, for example, takes about 3.0 s at half speed but only about 1.5 s at normal speed. x (m) 5 To walk to... x=4.8 m... 4 3 2 0 0 1 normal speed half as fast T | + 21 3 4 5 6 ... takes about 2.33 s at my normal speed... but twice as long at half the speed. t(s)
