Is a 128-Horsepower Car Sufficient for Mountain Climbing?

[DeJayla]

A 128-horsepower car is sufficient for mountain climbing. Horsepower is just one of the factors that determine a car's top speed; other factors such as the car's weight and its drag coefficient also influence speed. Below is more information about horsepower: 1. Definition of Horsepower: Horsepower is a commonly used unit of power in engineering, proposed by James Watt. 1 horsepower is approximately equal to 735 watts. It generally refers to metric horsepower rather than imperial horsepower. 2. Imperial Horsepower: The concept of horsepower as a unit was named by James Watt, the improver of the steam engine, to represent the power of his steam engine relative to the pulling power of horses. It is defined as 'the power of a horse capable of pulling 33,000 pounds at a speed of 1 foot per minute,' with watts (W) or kilowatts (kW) used as standard units. 3. Metric Horsepower: Metric horsepower, also known as PS (Pferdestärke), takes a value very close to imperial horsepower. It is defined as 1 metric horsepower being the power required to perform 75 kilogram-force meters of work per second. That is: 1 metric horsepower = 75 kilogram-force meters/second = 735 watts.
