Energy Available due to Reduction in Speed Solution

Follow our step by step solution on how to calculate Energy Available due to Reduction in Speed?

FIRST Step Consider the formula

E o = 0.01072 \cdot W e \cdot v^{2} - u^{2}

Next Step Substitute values of Variables

∴

E o = 0.01072 \cdot 33000AT (US) \cdot {144km/h}^{2} - {111.6km/h}^{2}

Next Step Convert Units

∴

E o = 0.01072 \cdot 962.5001kg \cdot {40m/s}^{2} - {31m/s}^{2}

Next Step Prepare to Evaluate

∴

E o = 0.01072 \cdot 962.5001 \cdot 40^{2} - 31^{2}

Next Step Evaluate

∴

E o = 15547.8018868873J

Next Step Convert to Output's Unit

∴

E o = 4.31883385746869W*h

LAST Step Rounding Answer

∴

E o = 4.3188W*h
