Q
Q: A 10 kg object is lifted to a height of 5 m. How much work is done against gravity?
Solution:
Work done = mgh = 10 * 9.8 * 5 = 490 J.
Steps: 7
Show Steps
Step 1: Identify the mass of the object. In this case, the mass (m) is 10 kg.
Step 2: Identify the height to which the object is lifted. Here, the height (h) is 5 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 Work = m * g * h.
Step 5: Substitute the values into the formula: Work = 10 kg * 9.8 m/s² * 5 m.
Step 6: Calculate the result: 10 * 9.8 * 5 = 490 J.
Step 7: Conclude that the work done against gravity is 490 Joules.
