Stopping Sight Distance on Level Ground with Breaking Efficiency Solution

Follow our step by step solution on how to calculate Stopping Sight Distance on Level Ground with Breaking Efficiency?

FIRST Step Consider the formula

SSD = V b \cdot t + \frac{{V b}^{2}}{2 \cdot [g] \cdot f \cdot η x}

Next Step Substitute values of Variables

∴

SSD = 11.11m/s \cdot 2.5s + \frac{{11.11m/s}^{2}}{2 \cdot [g] \cdot 0.15 \cdot 0.8}

Next Step Substitute values of Constants

∴

SSD = 11.11m/s \cdot 2.5s + \frac{{11.11m/s}^{2}}{2 \cdot 9.8066m/s² \cdot 0.15 \cdot 0.8}

Next Step Prepare to Evaluate

∴

SSD = 11.11 \cdot 2.5 + \frac{{11.11}^{2}}{2 \cdot 9.8066 \cdot 0.15 \cdot 0.8}

Next Step Evaluate

∴

SSD = 80.2190473216304m

LAST Step Rounding Answer

∴

SSD = 80.219m
