A block of 2 kg is suspended from the ceiling through a massless spring of spring constant k=100 N/m. What is the elongation of the spring? If another 1 kg is added to the block, what would be the further elongation?

Explanation

To solve the problem step by step, we will analyze the forces acting on the spring when the blocks are added and calculate the elongation of the spring in both scenarios.

### Step 1: Calculate the elongation of the spring with the 2 kg block

1. **Identify the forces acting on the spring**:
- The weight of the 2 kg block (W1) acting downwards.
- The spring force (F_spring) acting upwards.
