Calculating Potential Energy of a Body

The question asks us to calculate the potential energy of a body with a mass of 200 grams, lifted to a height of 3 meters above the ground.

Potential energy is the energy that a body possesses due to its position or state. For a body under the influence of gravity, its potential energy depends on its mass and height above a reference level, usually the ground.

The formula to calculate potential energy (PE) is: PE = mgh

Where: - m is the mass of the body in kilograms - g is the acceleration due to gravity, which is approximately 9.8 m/s^2 - h is the height of the body in meters

To solve this problem: - The mass (m) given is 200 grams. Converting to kilograms, this is 0.2 kg - The height (h) given is 3 meters - Using the value of g = 9.8 m/s^2

Plugging these values into the formula: PE = mgh PE = 0.2 kg x 9.8 m/s^2 x 3 m PE = 5.88 Joules

Therefore, the potential energy of a body with a mass of 200 grams lifted to a height of 3 meters above the ground is 5.88 Joules.
