Question

A rocket motor consumes \(3000\ \text{kg}\) of fuel per minute exhausting it with a speed of \(5\times10^3\ \text{m/s}\). The magnitude of force exerted on rocket is:

• A. \(5\times10^5\ \text{N}\)
• B. \(3\times10^6\ \text{N}\)
• C. \(6\times10^5\ \text{N}\)
• D. \(25\times10^4\ \text{N}\)

Hint:

Rocket thrust is equal to mass ejection rate multiplied by exhaust velocity.

Answer 1

The Correct Option is D
