An astronaut orbiting in a spaceship round the earth, has centripetal acceleration `2.45m//s^(2)`. Find the height of the spaceship. (Take R = 6400 km).

Explanation

To solve the problem of finding the height of the spaceship above the Earth's surface given the centripetal acceleration, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Given Data**:
- Centripetal acceleration \( a = 2.45 \, \text{m/s}^2 \)
- Radius of the Earth \( R = 6400 \, \text{km} = 6400 \times 10^3 \, \text{m} \)
