SUMMARY
The minimum horsepower required to prevent a leaking ship from sinking is calculated based on the need to pump 12.0 kg of water per second up a height of 1.50 meters. The work done is determined using the formula W = F * d, resulting in 176.4 watts. Converting this to horsepower yields approximately 0.236 horsepower. To accurately compute power, it is essential to use the formula P = W/t, ensuring the mass of water is correctly identified in kilograms.
