A block of mass 2 kg is being brought down by a string. If the block acquires a speed `1(m)//(s)` in dropping down 25 cm, find the work done by the string in the process.

Explanation

To solve the problem step by step, we will follow the outlined procedure:

### Step 1: Understand the Problem
We have a block of mass \( m = 2 \, \text{kg} \) that is being brought down by a string. The block drops a distance of \( s = 25 \, \text{cm} \) (which we will convert to meters) and acquires a speed of \( v = 1 \, \text{m/s} \). We need to find the work done by the string on the block.

### Step 2: Convert Units
Convert the displacement from centimeters to meters:
\[
