A man weighing 70 kg is standing at the centre of a flat boat of mass 350 kg. The man who is at a distance of 10 m from the shore walks 2 m towards it and stops. How far will he be from the shore? Assume the boat to be of uniform thickness and neglect friction between boat and water?

Explanation

To solve the problem, we need to analyze the situation using the principle of conservation of momentum since there are no external forces acting on the system (the man and the boat).

### Step-by-Step Solution:

1. **Identify the Initial Conditions**:
- The man weighs \( m_1 = 70 \, \text{kg} \).
- The boat weighs \( m_2 = 350 \, \text{kg} \).
- The initial distance of the man from the shore is \( d_{\text{initial}} = 10 \, \text{m} \).
