Coefficient of Friction given Stopping Sight Distance Solution

Follow our step by step solution on how to calculate Coefficient of Friction given Stopping Sight Distance?

FIRST Step Consider the formula

f = \frac{{V b}^{2}}{2 \cdot [g] \cdot (SSD - (V b \cdot t))}

Next Step Substitute values of Variables

∴

f = \frac{{11.11m/s}^{2}}{2 \cdot [g] \cdot (160m - (11.11m/s \cdot 2.5s))}

Next Step Substitute values of Constants

∴

f = \frac{{11.11m/s}^{2}}{2 \cdot 9.8066m/s² \cdot (160m - (11.11m/s \cdot 2.5s))}

Next Step Prepare to Evaluate

∴

f = \frac{{11.11}^{2}}{2 \cdot 9.8066 \cdot (160 - (11.11 \cdot 2.5))}

Next Step Evaluate

∴

f = 0.0475952783406742

LAST Step Rounding Answer

∴

f = 0.0476
