Q
Q: A 5 kg object is lifted to a height of 3 m. What is the work done against gravity?
Solution:
Work done against gravity is W = mgh = 5 * 9.8 * 3 = 147 J.
Steps: 6
Show Steps
Step 1: Identify the mass of the object. In this case, the mass (m) is 5 kg.
Step 2: Identify the height to which the object is lifted. Here, the height (h) is 3 m.
Step 3: Identify the acceleration due to gravity (g). The standard value is approximately 9.8 m/s².
Step 4: Use the formula for work done against gravity, which is W = mgh.
Step 5: Substitute the values into the formula: W = 5 kg * 9.8 m/s² * 3 m.
Step 6: Calculate the result: W = 5 * 9.8 * 3 = 147 J.
