A man of mass 20 kg is carrying a mass of 3 kg on his head. Calculate the work done by the man in moving a distance of 10 m up an incline of 1 in 5 ?

Explanation

To solve the problem of calculating the work done by a man carrying a mass of 3 kg on his head while moving up an incline of 1 in 5 for a distance of 10 m, we can follow these steps:

### Step 1: Determine the total mass being carried
The man has a mass of 20 kg and is carrying an additional mass of 3 kg. Therefore, the total mass \( m \) is:
\[ m = 20 \, \text{kg} + 3 \, \text{kg} = 23 \, \text{kg} \]
