Question
![**Problem Statement:**
A spaceship's orbital maneuver requires a speed increase of \( 1.00 \times 10^3 \) m/s. If its engine has an exhaust speed of \( 2.90 \times 10^3 \) m/s, determine the required ratio \( \frac{M_i}{M_f} \) of its initial mass to its final mass. (The difference \( M_i - M_f \) equals the mass of the ejected fuel.)
**Explanation and Solution:**
To solve this problem, we need to use the Tsiolkovsky rocket equation (also known as the ideal rocket equation), which relates the initial and final masses of a rocket to the velocity change and exhaust velocity. The equation is:
\[
\Delta v = v_e \ln \left( \frac{M_i}{M_f} \right)
\]
Where:
- \(\Delta v\) is the change in velocity (speed increase) required.
- \(v_e\) is the exhaust velocity.
- \(M_i\) is the initial mass of the spaceship.
- \(M_f\) is the final mass of the spaceship.
- \(\ln\) denotes the natural logarithm.
Given data:
- \(\Delta v = 1.00 \times 10^3 \text{ m/s}\)
- \(v_e = 2.90 \times 10^3 \text{ m/s}\)
Step 1: Rearrange the Tsiolkovsky rocket equation to solve for \( \frac{M_i}{M_f} \):
\[
\frac{M_i}{M_f} = e^{\frac{\Delta v}{v_e}}
\]
Step 2: Substitute the given values into the equation:
\[
\frac{M_i}{M_f} = e^{\frac{1.00 \times 10^3 \text{ m/s}}{2.90 \times 10^3 \text{ m/s}}}
\]
Step 3: Calculate the exponent:
\[
\frac{1.00 \times 10^3}{2.90 \times 10^3} = \frac{1}{2.9} \approx 0.3448
\]
Step 4: Use the exponential function:
\[
\frac{M_i}{M_f} = e^{0.3448} \approx](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F674187d8-06e8-4f69-af48-239b1a5ca06a%2F21bd0bc7-d8f7-4de1-a40f-3b2133b4a2c4%2Fdsft16j.jpeg&w=3840&q=75)
