Calculate the work done against gravity on a bag of rice
What is the formula to calculate the work done against gravity?
How can we determine the work done on a 25 kg bag of rice lifted to a height of 18.2 m?
Explanation:
The work done against gravity on a bag of rice can be calculated using the formula: work = mass x gravity x height.
When a bag of rice weighing 25 kg is lifted to a height of 18.2 m above the ground, we can calculate the work done against gravity using the formula mentioned earlier. In this case, the mass (m) of the bag is 25 kg, the acceleration due to gravity (g) is 10 m/s², and the height (h) is 18.2 m.
By substituting these values into the formula, we get: Work = 25 kg x 10 m/s² x 18.2 m Work = 4550 Joules
Therefore, the work done against gravity in lifting the 25 kg bag of rice to a height of 18.2 m is 4550 Joules, which is the correct answer.
