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 will use the principle of conservation of momentum and the concept of the center of mass. Here's the step-by-step solution:

### Step 1: Understand the Initial Setup
- The man weighs \( m_1 = 70 \, \text{kg} \).
- The boat weighs \( m_2 = 350 \, \text{kg} \).
- Initially, the man is at a distance of \( 10 \, \text{m} \) from the shore.

### Step 2: Define the Movements
