A man weighning 60 kg is holding of mass 10 kg on his head . What will be the work done by the man if he travels a distance of 20 m in
(i) vertical direction ( up or down ? )
(ii) horizontal direction

Explanation

To solve the problem step by step, we will analyze the two parts of the question separately.

### Given:
- Weight of the man (m1) = 60 kg
- Weight on his head (m2) = 10 kg
- Total mass (m_total) = m1 + m2 = 60 kg + 10 kg = 70 kg
- Distance traveled (d) = 20 m
- Acceleration due to gravity (g) = 10 m/s²
