Driving in thick fog on a horizontal road, you spot a tractortrailer truck jackknifed across the road. To avert a collision, you could brake to a stop or swerve in a circular arc, as suggested in Fig. $5.35 .$ Which option offers the greater margin of safety? Assume that there is the same coefficient of static friction in both cases, and that you maintain constant speed if you swerve.

Step 1

Given: $a = \frac{v^2}{r}$, $v = \frac{90 \times 5}{18}$ m/s, $g = 9.8$ m/s$^2$ Substitute the values into the formula: $a = \frac{(\frac{90 \times 5}{18})^2}{r}$ $a = \frac{25}{4r}$ $a = \frac{6.25}{r}$ Show more…
