STEP 1: Convert Input(s) to Base Unit

Accelerating Weight of Train: 33000 Ton (Assay) (US) --> 962.500110009752 Kilogram (Check conversion here)
Weight of Train: 30000 Ton (Assay) (US) --> 875.000100008866 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_R = 0.01072*(W_e/W)*(v^2-u^2) --> 0.01072*(962.500110009752/875.000100008866)*(40^2-31^2)

Evaluating ... ...

E_R = 7.535088

STEP 3: Convert Result to Output's Unit

7.535088 Joule -->0.00209308 Watt-Hour (Check conversion here)

FINAL ANSWER

0.00209308 ≈ 0.002093 Watt-Hour <-- Energy Consumption during Regeneration
