Energy Available due to Reduction in Speed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Energy Consumption by Train = 0.01072*Accelerating Weight of Train*Final Velocity^2-Initial Velocity^2
E_o = 0.01072*W_e*v^2-u^2
This formula uses 4 Variables

Variables Used

Energy Consumption by Train - (Measured in Joule) - Energy Consumption by Train is the total energy consumed by the train during travel.
Accelerating Weight of Train - (Measured in Kilogram) - Accelerating Weight of Train is the effective weight of train that has angular acceleration due to the rotational inertia including the dead weight of the train.
Final Velocity - (Measured in Meter per Second) - Final Velocity is defined as a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.
Initial Velocity - (Measured in Meter per Second) - Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts.

STEP 1: Convert Input(s) to Base Unit

Accelerating Weight of Train: 33000 Ton (Assay) (US) --> 962.500110009752 Kilogram (Check conversion here)
Final Velocity: 144 Kilometer per Hour --> 40 Meter per Second (Check conversion here)
Initial Velocity: 111.6 Kilometer per Hour --> 31 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E_o = 0.01072*W_e*v^2-u^2 --> 0.01072*962.500110009752*40^2-31^2

Evaluating ... ...

E_o = 15547.8018868873

STEP 3: Convert Result to Output's Unit

15547.8018868873 Joule -->4.31883385746869 Watt-Hour (Check conversion here)

FINAL ANSWER

4.31883385746869 ≈ 4.318834 Watt-Hour <-- Energy Consumption by Train
