A rocket fired from the earth's surface ejects `1%` of its mass at a speed of 2000 `ms^(-1)` in the first second. Find the average acceleration of the rocket in the first second.

Explanation

To solve the problem of finding the average acceleration of a rocket that ejects 1% of its mass at a speed of 2000 m/s in the first second, we can follow these steps:

### Step 1: Identify the mass ejected
Let the total mass of the rocket be \( m \). The mass ejected in the first second is 1% of \( m \):
\[ \text{Mass ejected} = \frac{1}{100} m = 0.01 m \]
