Final answer:
The work done against gravity when lifting a 200 kg object by 3 meters high is calculated using the formula Work = mass × gravitational acceleration × height.
Step-by-step explanation:
The question asks to calculate the work done against gravity when lifting a 200 kg object by 3 meters high. The formula for work done against gravity is Work (W) = Force (F) × Distance (D), where Force is equal to the mass (m) multiplied by the acceleration due to gravity (g), which is approximately 9.8 m/s2 on Earth's surface. Moreover, the distance (D) is the height the object is lifted. Therefore, the work done would be W = m × g × D, which for this specific problem equates to W = 200 kg × 9.8 m/s2 × 3 m.
