The formula to estimate speed from horsepower and weight is:
\[ \text{Speed (MPH)} = \left( \frac{\text{Horsepower (HP)}}{\text{Vehicle Weight (lbs)}} \times 234 \right)^{\frac{1}{3}} \]
The horsepower to speed conversion is an estimation of a vehicle's speed based on its engine horsepower and weight. This ratio helps in understanding the potential speed of the vehicle.
Consider a vehicle with an engine horsepower of 300 HP and a weight of 4000 lbs:
Using the formula:
\[ \text{Speed (MPH)} = \left( \frac{300}{4000} \times 234 \right)^{\frac{1}{3}} = 2.92 \text{ MPH} \]
This means the estimated speed of the vehicle is 2.92 MPH.
