Rate of Change of Acceleration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rate of Change of Acceleration = (Design Speed^3)/(Length of Curve*Radius of Curve)
C_a = (v^3)/(L_s*R)
This formula uses 4 Variables

Variables Used

Rate of Change of Acceleration - (Measured in Meter per Second) - Rate of Change of Acceleration refers to how quickly the acceleration of an object changes over time.
Design Speed - (Measured in Meter per Second) - Design speed refers to the intended or planned operating speed for a particular section of a roadway or railway.
Length of Curve - (Measured in Meter) - Length of Curve is the distance along the road where the alignment changes from upward to downward slope, creating a valley-shaped concave.
Radius of Curve - (Measured in Meter) - Radius of Curve typically represents the minimum radius of the curve.

STEP 1: Convert Input(s) to Base Unit

Design Speed: 5 Meter per Second --> 5 Meter per Second No Conversion Required
Length of Curve: 12.71876 Meter --> 12.71876 Meter No Conversion Required
Radius of Curve: 2.34 Meter --> 2.34 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_a = (v^3)/(L_s*R) --> (5^3)/(12.71876*2.34)

Evaluating ... ...

C_a = 4.20000089779219

STEP 3: Convert Result to Output's Unit

4.20000089779219 Meter per Second --> No Conversion Required

FINAL ANSWER

4.20000089779219 ≈ 4.200001 Meter per Second <-- Rate of Change of Acceleration
