Q
Q: If a 5 kg object is lifted to a height of 10 m, what is the work done against gravity?
Solution:
Work done = mgh = 5 kg × 9.8 m/s² × 10 m = 490 J.
Steps: 7
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 10 m.
Step 3: Identify the acceleration due to gravity. This is approximately 9.8 m/s².
Step 4: Use the formula for work done against gravity, which is Work = mgh.
Step 5: Substitute the values into the formula: Work = 5 kg × 9.8 m/s² × 10 m.
Step 6: Calculate the result: 5 × 9.8 × 10 = 490 J.
Step 7: Conclude that the work done against gravity is 490 Joules.
